MAGNETIC PROPERTIES AND MAGNETIC STRUCTURE OF ErFe_(11)Ti SINGLE CRYSTAL AND ITS HYDRIDE

摘要

The hydrogenation effect on some magnetic properties of the intermetallic compound ErFe_(11)Ti are studied. Single crystals of the hydrogen containing compound were obtained and both compounds have been studied on a single crystal samples. Magnetic characteristics of the ErFe_(11)Ti and ErFe_(11)TiH_(1-δ) have been investigated over the temperature range 4.2 ― 750 K and at magnetic fields up to 13 kOe. Upon hydrogenation Curie temperature T_C is observed to increase, while the spin-reorientation temperatures TSR shifted towards lower temperatures.
