Investigating the Impact of Temperature on Magnetic-Field Behavior of Thin-Film Three-Layer Systems Co/Cu/Co and Co/Gd/Co

This paper presents the results of investigating the impact of temperature on the magnetic properties of Co/Gd/Co and Co/Cu/Co thin-film three-layer systems obtained via ion-plasma magnetron sputtering. The following features of the studied samples were found. In particular, when the temperature changes from 100 to 300[Formula: see text]K, the coercive force of studied systems decreases. The magnetic moment of Co/Cu/Co sample does not dependent on temperature. Strong influence of temperature on the magnetic properties of the studied samples is observed. In particular, a compensation point was found at temperature [Formula: see text][Formula: see text]K for a Co/Gd/Co sample with thickness of gadolinium of 9.0[Formula: see text]nm.
