First-principles study on the stability of (, Zr)(Fe, Co, Ti) against 2-17 and unary phases ( = Y, Nd, Sm)
Taro Fukazawa, Yosuke Harashima, Takashi Miyake
The stability of (, Zr)(Fe, Co, Ti) with a ThMn structure is investigated using first-principles calculations. We consider energetic competition with multiple phas…
First-principles investigation of Nd(Fe,M)12 (M = K--Br) and Nd(Fe,Cr,Co,Ni,Ge,As)12: Possible enhancers of Curie temperature for NdFe12 magnetic compounds
Taro Fukazawa, Hisazumi Akai, Yosuke Harashima +1
We investigate the effects of various dopants (M = K--Br) on the Curie temperature of the magnetic compound NdFe12 through first-principles calculations. Analysis by the Korringa--…
Lattice dynamics effects on finite-temperature stability of Fe ( = Y, Ce, Nd, Sm, and Dy) alloys from first principles
Guangzong Xing, Takahiro Ishikawa, Yoshio Miura +2
We report the effects of lattice dynamics on thermodynamic stability of binary Fe compounds (: rare-earth elements, Y, Ce, Nd, Sm, and Dy) at finite tempe…
Evolutionary search for cobalt-rich compounds in the yttrium-cobalt-boron system
Takahiro Ishikawa, Taro Fukazawa, Guangzong Xing +2
Modern high-performance permanent magnets are made from alloys of rare earth and transition metal elements, and large magnetization is achieved in the alloys with high concentratio…
Spin-wave dispersion and exchange stiffness in NdFeB and FeTi (=Y, Nd, Sm) from first-principles calculations
Taro Fukazawa, Hisazumi Akai, Yosuke Harashima +1
We theoretically investigate spin-wave dispersion in rare-earth magnet compounds by using first-principles calculations and a method we call the reciprocal-space algorithm (RSA). T…
Ensemble learning reveals dissimilarity between rare-earth transition metal binary alloys with respect to the Curie temperature
Duong-Nguyen Nguyen, Tien-Lam Pham, Viet-Cuong Nguyen +3
We propose a data-driven method to extract dissimilarity between materials, with respect to a given target physical property. The technique is based on an ensemble method with Kern…
