The relations between S\u0000v\u0000, the activation volume (v), H\u0000cJ\u0000, H\u0000A\u0000, and R\u0000h\u0000 were studied, as well as the effect of milling. S\u0000v\u0000 is constant and independent of the magnetic field. In S\u0000v\u0000 varies in proportion to In H\u0000cJ\u0000, and the relation H\u0000cJ\u0000∝v\u0000-2\u0000 was found to obtain in SrM particles not extensively subjected to milling. S\u0000v\u0000 increases and v decreases for SrM fine particles (D=0.3 μm) whose H\u0000A\u0000 is widely distributed by milling, even though H\u0000cJ\u0000 decreases markedly. S\u0000v\u0000 and v are related to the distribution of H\u0000A\u0000. As H\u0000cJ\u0000 increases, R\u0000h\u0000 and v decrease, which indicates that the magnetization reversal mechanism of SrM fine particles approaches that of a coherent rotation mode.","PeriodicalId":100647,"journal":{"name":"IEEE Translation Journal on Magnetics in Japan","volume":"9 5","pages":"144-149"},"PeriodicalIF":0.0,"publicationDate":"1994-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/TJMJ.1994.4565938","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67892835","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}

Most of these alloys are obtained by annealing an amorphous phase, and consequently there is a limit to the B\u0000s\u0000 imposed by glass-forming materials. We have been studying soft magnetic alloy films with high B\u0000s\u0000, which have nanocrystalline structures in the as-deposited state. In this paper, we describe the magnetic and structural properties of nanocrystalline Fe-M-O (M=Y,Ce) alloy films. The Y or Ce and O elements in the films tend to make the bcc grains finer in the as-deposited state, and also repress the growth of grains during annealing through the presence of very fine (less than 10 nm in size) oxide particles containing Y or Ce. The highest B\u0000s\u0000 and μ\u0000e\u0000 values at 1 MHz, and the lowest H\u0000c\u0000 value, were 1.95 T, 1200 and 0.6 Oe respectively for a Fe\u000085\u0000Y\u00004\u0000O\u000011\u0000 film annealed at 773K for one hour.","PeriodicalId":100647,"journal":{"name":"IEEE Translation Journal on Magnetics in Japan","volume":"9 4","pages":"92-99"},"PeriodicalIF":0.0,"publicationDate":"1994-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/TJMJ.1994.4565898","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67857914","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}

Samples were annealed at 673K for one hour. Crystal structures were bcc for the Fe-Si-Ti and Fe-Co-Ti ternary films, and a mixture of bcc and bcc+Fe\u00002\u0000Ti for the Fe-Al-Ti ternary films. The addition of Ti reduces &3x001F5;rain sizes to a minimum of about 10 nm. Addition of Al, Si or Ti to Fe reduces the saturation magnetic flux density of Fe-Al-Ti and Fe-Si-Ti films, and addition of Co increases the saturation magnetic flux density of Fe-Co-Ti. Zero-magnetostriction samples were obtained in each ternary system. Low coercivity (under 5 Oe) and high initial permeability (about 1000) were obtained together with zero magnetostriction for Fe-Al-Ti ternary films by adding a small amount of Ti. In the case of Fe-Co-Ti ternary films, low coercivity and high permeability were obtained along with small grain sizes of 10 nm or so. Films with low magnetostriction (λ\u0000s\u0000≪3×10\u0000-6\u0000) had a coercivity roughly proportional to the third power of the grain diameter.","PeriodicalId":100647,"journal":{"name":"IEEE Translation Journal on Magnetics in Japan","volume":"9 4","pages":"107-113"},"PeriodicalIF":0.0,"publicationDate":"1994-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/TJMJ.1994.4565900","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67857915","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}
