Reinvestigation of the intrinsic magnetic properties of (FeCo)B alloys and crystallization behavior of ribbons
Tej Nath Lamichhane, Olena Palasyuk, Vladimir P. Antropov +10
New determination of the magnetic anisotropy from single crystals of (FeCo)B alloys are presented. The anomalous temperature dependence of the anisotropy constant i…
Spatial decomposition of magnetic anisotropy in magnets: application for doped Fe16N2
Yang Sun, Yong-Xin Yao, Manh Cuong Nguyen +3
We propose a scheme of decomposition of the total relativistic energy in solids to intra- and interatomic contributions. The method is based on a variation of the speed of light fr…
Theoretical prediction of a highly responsive material: Spin fluctuations and superconductivity in FeNiB2 system
Renhai Wang, Yang Sun, Vladimir Antropov +3
By analyzing Fe-Ni-B compositional diagram we predict an energetically and dynamically stable FeNiB2 compound. This system belongs to the class of highly responsive state of materi…
Concentration tuned tetragonal strain in alloys: application to magnetic anisotropy of FeNiCo
Aleksander L. Wysocki, Manh Cuong Nguyen, Cai-Zhuang Wang +3
We explore an opportunity to induce and control tetragonal distortion in materials. The idea involves formation of a binary alloy from parent compounds having body-centered and fac…
Single Crystal Permanent Magnet: Extraordinary Magnetic Behavior in the ta, Cu and Fe Substituted CeCo5 System
Tej N. Lamichhane, Michael T. Onyszczak, Olena Palasyuk +12
To reduce material and processing costs of commercial permanent magnets and to attempt to fill the empty niche of energy products, 10 - 20 MGOe, between low-flux (ferrites, alnico)…
Using first-principles calculations to screen for fragile magnetism: Case study of LaCrGe3 and LaCrSb3
Manh Cuong Nguyen, Valentin Taufour, Sergey L. Budko +4
In this paper, we present a coupled experimental/theoretical investigation of pressure effect on the ferromagnetism of LaCrGe3 and LaCrSb3 compounds. The magnetic, electronic, elas…
