Critical behavior and magnetocaloric effect simulation in TbFeSi and DyFeSi intermetallic compounds using a Landau universal
In this paper, we introduce a novel calculation method of magnetic entropy change in an arbitrary ferromagnetic system based on the Landau model for Gibbs free energy and the Arrott–Noakes equation, −ΔSM=11γ+1dA(T)dTM1γ+1−MS1γ+1+11β+1γ+1dB(T)dTM1β+1γ+1−MS1β+1γ+1−M−MSH1γH1−1γ. This theoretical study...
