The supercell Fe-B-P-Cu was equilibrated at 3000 K for 12 ps using <em>ab initio molecular dynamics</em> (AIMD). Consequently, Fe, B, P, and Cu atoms are distributed randomly in an amorphous matrix formed by cooling it to 0 K. The ferromagnetic <em>bcc α</em>-(Fe₅₀Co₅₀) crystallites were formed in the amorphous matrix by annealing the mixture at 300 K and cooling to 0 K. This resulted in the formation of nanocrystalline (Fe, Co)-B-P-Cu soft magnetic alloys. The ferromagnetic <em>bcc α</em>-Fe(Co) crystallites, embedded in an amorphous matrix, were confirmed experimentally for the first time. The experiment involved quickly cooling and heating a melted mixture of Fe, Co, B, Fe₃P, and Cu to create both amorphous ribbons and crystallites. The Fe-Co-B-P-Cu alloy designed for the experiment has a saturation magnetization (<em>μ</em>₀<em>M</em>_S) of over 1.9 T (T) at 0 K and ranging from 1.87 to 1.92 T at 300 K. The magnetocrystalline anisotropy constant (K) decreased significantly to 142 J/m³ from 5.2 × 104 J/m³ with an increase in the number of embedded crystallites from one to five, indicating that the alloy became magnetically soft. At 300 K, the experimental <em>μ</em>_<em>0</em><em>M</em>_<em>S</em> ranged from 1.79 to 1.89 T. Additionally, as the concentration of Co increased, the Curie temperature (T_C) also increased and reached about 800 °C at 3.5 at.%. The study revealed that the average grain size of the synthesized Fe-Co-B-P-Cu alloys was 29 nm. The experimental <em>μ</em>₀<em>M</em>_S was slightly lower than the calculated value for all designed Fe-Co-B-P-Cu alloys, indicating that the recrystallization process was not entirely controlled. The experimental results confirmed that the designed alloy system has achieved the target saturation magnetization of over 1.8 T. These results effectively demonstrate the efficiency of the design method for nanocrystalline soft magnetic materials. Consequently, the alloy design method outlined in this paper will offer guidance for developing other soft magnetic materials.</div></div>","PeriodicalId":20116,"journal":{"name":"Physica B-condensed Matter","volume":"714 ","pages":"Article 417510"},"PeriodicalIF":2.8,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144312651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Employing this procedure we have obtained quite different spectra depending on the value of mass. Specifically, when the mass is positive but smaller inside the dot than outside it, the spectrum increases and splits into two types of eigenvalues separated by a gap. Conversely, if the mass inside the quantum dot is greater than outside, the spectrum has fewer points and it is necessary stronger fields in order to confine states. All these spectral points correspond to bulk eigenfunctions. However, in the case of inverted mass (negative mass inside the quantum dot and positive outside it) there are new eigenvalues corresponding to edge states.
