Research Abstract

Various types of spintronic devices based on magnetic functions at thin film interfaces have been extensively studied. Direct measurement of interface spin is crucial to realize such applications, because the device function is governed by local spin orientations at the interface. In this study we have developed a high-resolution microscopic technique capable of quantitative analysis of interface spin arrangement at nanometric resolution.
