Giant forced magnetostriction in Tb_0.2Gd_0.8 single crystal

Abstract

The results of investigation of the Tb0.2Gd0.8 single crystal forced magnetostriction are presented. Temperature dependences of magnetostriction have been measured from 4 to 300°K in applied magnetic fields up to 14 T. The giant field induced magnetostriction ~ 1.5•10-3 was discovered in the room temperature region in magnetic fields up to 14 T.
