Title: Effect of capping material on interfacial ferromagnetism in FeRh thin films

Abstract

The role of the capping material in stabilizing a thin ferromagnetic layer at the interface between a FeRh film and cap in the nominally antiferromagnetic phase at room temperature was studied by x-ray magnetic circular dichroism in photoemission electron microscopy and polarized neutron reflectivity. These techniques were used to determine the presence or absence of interfacial ferromagnetism (FM) in films capped with different oxides and metals. Chemically stable oxide caps do not generate any interfacial FM while the effect of metallic caps depends on the element, showing that interfacial FM is due to metallic interdiffusion and the formation of a ternary alloy with a modified antiferromagnetic to ferromagnetic transition temperature.

Figures / Tables:

FIG. 1 FIG. 1: Temperature-dependent magnetization of FeRh films with different caps showing the hysteretic transition from AF (near zero magnetization) to FM phase. The transition was measured in an external field of 5 T and the temperature axis has been corrected to reflect the transition in no external field since thatmore » is what is measured in both PEEM and PNR. Note that all films are fully FM above 410 K and fully AF below 340 K. M is normalized by its high T, fully FM value to account for small differences in composition. Different line types are used to distinguish the different samples and red/blue colors are used to distinguish the heating/cooling curves.« less
