Abstract :
This paper presents a theoretical study of thermal hysteresis of thin Dy films. Large differences between the isofield magnetization curves during heating or cooling are found. The width of the thermal hysteresis may cover the whole interval between the Curie (TC) and the Neel (TN) temperatures and it is controlled by external field. The thermal hysteresis is controllable by external magnetic fields and thickness, it is modest for ultra thin films and large above a critical film thickness.
