Abstract
The temperature dependence of the magnetostriction from 77 to 360 K is investigated in the pseudobinary compounds Sm 1- x Er x Fe 2 ( x = 0, 0.02, 0.03, 0.04, 0.05, 0.1, 0.2, 0.4, 0.6, 0.8 and 1.0). At 200 K the Sm 0.95Er 0.05Fe 2 compound has the largest magnetostriction and the compound with x = 0.4 has the minimum one at room temperature. Temperature and field dependence of magnetization are investigated in the temperature ranging from 4.2 Curie points and in fields up to 110 kOe. For the compound with x = 0.2, minimum saturation magnetic moment and maximum samarium moment are observed. At low temperatures reorientation of the easy axis of magnetization is observed in the rich-Sm compounds. The electrical resistivity is measured from 4.2 to 700 K. The paramagnetic susceptibility measurements are given.
