Влияние ультратонкой прослойки на параметры межслойной обменной связи в пленках Fe10Ni90/X/Tb-Co (X=Ti,Ni,Tb)

Abstract

Hysteresis properties of Fe10Ni90/X/Tb-Co (X=Ti,Ni,Tb) multilayers at the temperature range of 80÷470 K were studied. It was shown that the exchange bias field value decreases monotonically with X spacer thickness and temperature increase, while the critical thickness of the exchange bias disappearance and the blocking temperature for different types of spacers are not similar. These features are associated with changes in the structural interface at high temperatures, as well as the influence of the spacer type and its thickness on the efficiency of the interlayer exchange coupling.
