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 300K, 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 T=150K for a Co/Gd/Co sample with thickness of gadolinium of 9.0nm.
