Detecting halfmetallic electronic structures of spintronic materials in a magnetic field

Abstract Band-gap engineering is one of the fundamental techniques in semiconductor technology and also applicable next generation spintronics using spin degree freedom. To fully utilize spintronic materials, it essential to optimize spin-dependent electronic structures operando conditions by applying magnetic and/or electric fields. Here we present an advanced spectroscopic technique probe spin-polarized circular dichroism (MCD) resonant inelastic soft X-ray scattering (RIXS) under external field. Thanks spin-selective dipole-allowed transitions RIXS-MCD, have successfully demonstrated direct evidence perfectly for prototypical halfmetallic Heusller alloy $$\hbox {Co}_2\hbox {MnSi}$$ Co 2 MnSi . RIXS-MCD a promising tool carriers band-gap induced buried layers element specific way conditions.
