Statistical and analytical approaches to finite-temperature magnetic properties of the compound SmFe12
Original language description
To investigate the magnetic properties of SmFe12, we construct an effective spin model, where magnetic moments, crystal-field (CF) parameters, and exchange fields at 0 K are determined by first-principles calculations.Finite-temperature magnetic properties are investigated by using this model. We further develop an analytical method with strong mixing of states with a different quantum number of angular momentum J (J-mixing), which is caused by a strong exchange field acting on the spin component of 4 f electrons. Comparing our analytical results with those calculated by Boltzmann statistics, we clarify that the previous analytical studies for Sm transition-metal compounds overestimate the J-mixing effects.n
