The external magnetic field exerts a magnetic force on the magnetizable MMPs to steer them from the bifurcation point to the desired channel. During this process, some MMPs aggregate and stick to the channel walls, thus reducing the efficacy of the navigation process. To mitigate this problem, a time-varying magnetic field (TVMF) is applied for efficient navigation of the MMPs in the channel. The TVMF alternately switches between two modes of operation described as follows. In the first mode of operation, the TVMF is applied for a certain time duration to generate the magnetic force required for steering the MMPs to the desired outlet. The second mode of operation facilitates mitigation of the stiction and aggregation of MMPs by modulating the TVMF and time duration of operation, so as to yield a lower magnetic force in the reverse direction to that in the first mode. Extensive simulations are performed to analyze the switching time for effective steering of the MMPs using COMSOL Multiphysics. Results illustrate that the time duration between the two modes of operation should be set using a ratio of 3\u0000<inline-formula><tex-math>$:$</tex-math></inline-formula>\u00001 for effective guidance of the MMPs to the correct outlet.","PeriodicalId":13040,"journal":{"name":"IEEE Magnetics Letters","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67741201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Especially for the localization of MNPs, magnetic particle imaging (MPI) has been developed to use magnetization generated by a magnetic field. However, most MPI systems use a bore-type structure, and there exist limitations in terms of working space, compatibility with surrounding medical devices, and being able to respond to emergency situations from a medical perspective. To address these issues, we present a novel, open-structure, magnetic particle spectroscopy (OMPS) technique. The structural design, theoretical background, and analysis of the OMPS are presented, and experiments are conducted to evaluate the OMPS. The experimental results indicate that the detection volume can be obtained as a cylindrical region of interest (ROI) of 50 mm &#x00D7; 50 mm &#x00D7; 25 mm, and the feasibility can be exhibited within the same or larger ROI with similar amounts of Resovist as used in previous MPI studies. The results demonstrate the promising potential for OMPS.","PeriodicalId":13040,"journal":{"name":"IEEE Magnetics Letters","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67902595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current ac magnetic flux leakage (ACMFL) testing systems generally operate at a high frequency but cannot detect backside defects owing to the skin effect. Low-frequency ACMFL is limited by low sensitivity and low efficiency in detecting deep defects. This letter presents a multifrequency ACMFL testing method combined with the merits of low- and high-frequency excitation to detect surface and backside defects. In early work, the optimal frequency for detecting the surface defect with a depth of 4 mm or less was 400 Hz. Through simulation analysis, the optimal low frequency for detecting backside defects is determined. Additionally, the influence of the excitation intensity on the response signal is investigated. Relatively small excitation power should be used to obtain a reliable detection waveform. Finally, the experimental results of surface and backside defects detection validated the practicality of the method.","PeriodicalId":13040,"journal":{"name":"IEEE Magnetics Letters","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67902594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two possible techniques are considered: the synthesis of magnetic nanotubes and their subsequent coating with silver, as well as the synthesis of vertical-standing arrays of layered magneto-optical nanowires (NWs) with alternating layers of nickel and silver. The resulting nanotubes and NWs are polycrystalline microstructures with a nanostructured plasmon-active surface. The absorption spectra have a distinct peak corresponding to the position of the local plasmon resonance: in the near-infrared range for the nickel nanotubes coated with silver and in the optical range for the layered NWs. For layered NWs, there is a combination of absorption peaks of both silver and nickel. The use of the obtained 1-D magneto-optical nanostructures for the formation of plasmon-active magnetically controlled substrates as surface-enhanced Raman spectroscopy (SERS) active surfaces is suggested for the detection of Rhodamine 6G in concentration down to 10\u0000<sup>–9</sup>\u0000 M. The increase of SERS signal intensity by using a magnetic field is shown for concentration 10\u0000<sup>−3</sup>\u0000 M with an extra signal amplification of more than four times.","PeriodicalId":13040,"journal":{"name":"IEEE Magnetics Letters","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2021-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67902603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
