Magnetic susceptibility and parameters of electronic structure of Al2R (R = La, Ce, Sm, Gd, Dy, Ho, Yb) intermetallic compounds at high temperatures.

Abstract

Magnetic properties of intermetallic compounds Al2R (R = La, Ce, Sm, Gd, Dy, Ho, Yb) are investigated in a wide temperature (20-1650°C) and magnetic fields (0,3-1,3 T) ranges. For all the samples the increase of magnetic susceptibility with temperature growth was found in liquid state. From experimental data several parameters of electronic structure of the compounds were obtained. In particular, it was shown that the values of effective magnetic moment per rare earth atom in compounds are lower than for ion R 3+.
