Magnetic anisotropy of RFe10Si2 alloys

Magnetocrystalline anisotropy, Curie temperatures, spin reorientation temperatures, and first-order magnetization processes (FOMP) are reported for RFe10Si2 compounds with R=Y, Gd, Tb, Dy, Ho, Er, and Lu. The saturation magnetizations of them at 1.5 K are determined. The value of the R-Fe magnetic-c...

Description
Summary:Magnetocrystalline anisotropy, Curie temperatures, spin reorientation temperatures, and first-order magnetization processes (FOMP) are reported for RFe10Si2 compounds with R=Y, Gd, Tb, Dy, Ho, Er, and Lu. The saturation magnetizations of them at 1.5 K are determined. The value of the R-Fe magnetic-coupling constant JRFe/k, derived by a mean-field analysis of the Curie temperatures, is about −10 K. A tentative spin-phase diagram for the RFe10Si2 series is presented.
