First-principles Calculation of Magnetocrystalline Anisotropy of Y(Co,Fe,Ni,Cu) Based on Full-potential KKR Green's Function Method
Haruki Okumura, Tetsuya Fukushima, Hisazumi Akai +1
The performance of permanent magnets YCo can be improved by replacing cobalt with other elements, such as iron, copper, and nickel. In order to determine its optimum compositio…
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--…
Polarization-Resolved Extreme Ultraviolet Second Harmonic Generation from LiNbO
Can B. Uzundal, Sasawat Jamnuch, Emma Berger +17
Second harmonic generation (SHG) spectroscopy ubiquitously enables the investigation of surface chemistry, interfacial chemistry as well as symmetry properties in solids. Polarizat…
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…
Data Assimilation Method for Experimental and First-Principles Data: Finite-Temperature Magnetization of (Nd,Pr,La,Ce)(Fe,Co,Ni)B
Yosuke Harashima, Keiichi Tamai, Shotaro Doi +8
We propose a data-assimilation method for evaluating the finite-temperature magnetization of a permanent magnet over a high-dimensional composition space. Based on a general framew…
Optimal uni-axial ferromagnetism in (La,Ce)FeB for permanent magnets
Munehisa Matsumoto, Masaaki Ito, Noritsugu Sakuma +3
Prospects for light-rare-earth-based permanent magnet compound RFeB (R=LaCe with ) are inspected from first principles referring to the lat…
