Random magnetocrystalline anisotropy in two-phase nanocrystalline systems
Kiyonori Suzuki,J. M. Cadogan +1 more
TL;DR: In this paper, the effect of the exchange stiffness in the intergranular phase on the exchange correlation length and the random magnetocrystalline anisotropy of two-phase soft magnetic materials, the hyperfine fields, coercivity and remanence to saturation ratio of nanocrystallines have been studied in the temperature range from 77 to 473 K.
Journal ArticleDOI
Magnetic properties of iron-rich Fe-Sc glasses.
TL;DR: A systematic study of the magnetic properties of melt-spun amorphous Fe/sub x/Zr/sub 100-//sub X/ alloys using Moessbauer and magnetization measurements has established the magnetic phase diagram.
Journal ArticleDOI
Structural properties of a novel magnetic ternary phase: Nd3(Fe1−xTix)29 (0.04 ≤ x≤ 0.06)
TL;DR: In this paper, a structural determination of the new magnetic ternary rare-earth iron-rich intermetallic Nd3(Fe1−xTix)29 phase was carried out by means of powder X-ray diffraction on a Nd0.955Ti0.045) sample.
Journal ArticleDOI
New rare‐earth intermetallic phases R3(Fe,M)29Xn: (R=Ce, Pr, Nd, Sm, Gd; M=Ti, V, Cr, Mn; and X=H, N, C) (invited)
TL;DR: In this article, the authors reviewed the work carried out to date on the 3:29 compounds and showed improved magnetic properties after interstitial modification with H or N; in particular, room temperature coercivity has been reported in Sm3(Fe,Ti)29N5, making this compound a candidate for possible permanent magnet applications.
Journal ArticleDOI
The effect of coherent uniaxial anisotropies on the grain-size dependence of coercivity in nanocrystalline soft magnetic alloys
TL;DR: In this article, the grain-size dependence of coercivity in various nanocrystalline soft magnetic materials has been re-analyzed with particular attention to induced uniaxial anisotropies.
