Abstract

Recently, current-induced spin transfer torque is attracting interest because it affects not only a FM but also an AFM [1, 2]. Furthermore, the critical current for AFM switching is more than 10-2 times smaller than typical value for a FM [1]. Therefore, FM/AFM bilayers containing half-metallic FMs are desirable for studying current-induced magnetization switching and spin torque in AFM materials. Up to now, we focused on antiperovskite nitride [3, 4] because there are many combinations of elements that form the antiperovskite nitride such a AFM materials and half-metallic FM. Anti-perovskite FM nitride Co3FeN is predicted that it has high negative spin polarization [3, 4]. Anti-perovskite AFM nitride Mn3GaN exhibits many interesting properties, such as piezomagnetic [5]. For Mn3GaN/Co3FeN bilayer, we expect application to the new devices controlling magnetic moments of Mn3GaN by spin transfer torque. In this study, we investigated current-induced magnetization switching in Mn3GaN/Co3FeN epitaxial exchange-coupled bilayers by employing AMR effect. We shall discuss spin transfer torque in antiferromagnetic Mn3 GaN.
