The structures consist of layers of commercially available piezoelectric (lead zirconate titanate) and magnetostrictive (permendur or nickel) materials. The magnetic-field pulses have the form of a half-wave sine function with duration of 450 μs and amplitude from 500 Oe up to 38 kOe. The measurement method is explained and the measured time dependence of the resulting voltage is presented. The most interesting case, when pulse amplitudes are sufficiently large (~ 1-10 kOe) and various types of acoustic oscillation with frequencies much larger than the reciprocal pulse length are excited in the structures, is considered. The dependencies of the magnetoelectric voltage coefficient on the excitation frequency and the applied magnetic field are calculated. By digital signal processing the results are compared with those obtained by the method of harmonic field modulation (HFM). The findings are of interest for developing magnetoelectric sensors for pulsed magnetic fields as well as for rapid characterization of magnetoelectric composite structures.","PeriodicalId":20497,"journal":{"name":"Proceedings of ISAF-ECAPD-PFM 2012","volume":"13 6","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2012-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72607217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SEM, XRD and TEM results revealed that the as-synthesized nanoparticles were crystalline wurzite ZnO with hexagonal flake morphology. ICP analysis confirmed the existence of Li element in these ZnO nanoparticles. For the measurement on their dielectric properties, the nanoparticles were further annealed in air under 900°C for 1 hour and then pressed into tablets under a pressure of 5×103 kg/cm2. When voltage cycles with varying magnitude were applied to these tablets of the Li-doped ZnO nanoparticles, the dependence of the polarization versus the applied field turned out to be hysteresis loops. The remanent polarizations and coercive fields were measured to be 10-5 to 10-4 Cm-2 and 104 to 105 Vm-1 order of magnitude, respectively. Since a variety of phenomena other than ferroelectricity would also lead to hysteresis loops, similar measurements for comparison were further performed with a view to probing the origin of the observed loops. The dielectric behaviors of ZnO nanoparticles fabricated in the Li-free solutions and the commercial ZnO particles were also measured and the polarization-field plots both appeared to be straight lines instead of loops.","PeriodicalId":20497,"journal":{"name":"Proceedings of ISAF-ECAPD-PFM 2012","volume":"23 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2012-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76178782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
