Abstract:
In this work, Gd-Co/Co/Cu/ Co-type thin film structures with the properties of thermo-sensitive spin valves have been developed, fabricated and investigated. For them, the results of magnetic and magnetoresistive measurements in a wide range of magnetic fields and temperatures are presented. It is shown that the appearance of a non-collinear magnetic structure in the Gd-Co/Co system significantly affects the shape of the magnetoresistive hysteresis loop. The value of the critical field of magnetization reversal depends on the temperature and can vary due to a change in the ratio between the layers thicknesses of the thin film system.
Keywords:
