Effect of element doping and substitution on the electronic structure and macroscopic magnetic properties of SmFe12 -based compounds
Original language description
The mechanisms underlying the enhancement of magnetic anisotropies (MAs) of Sm ions, owing to valence electrons at the Sm site are clarified using a detailed analysis of crystal fields (CF). In order to investigate the finite-temperature magnetic properties, we developed an effective spin model for SmFe12X (X=H, B, C, and N) and SmFe11M (M=Ti, V, and Co), where the magnetic moments, CF parameters, and exchange fields were determined by first-principle calculations. Using this model, the MA constants and magnetization curves at finite temperatures were investigated using a recently introduced analytical method [Yoshioka, Tsuchiura, and Novák, Phys. Rev. B 102, 184410 (2020)].The calculated temperature dependence of K1(T) and K2(T) in SmFe11Co qualitatively reproduces the experimental results.
