Abstract
The structural and magnetic properties of an Mn rich solid phase epitaxy MnxGe1âx alloy grown on a clean 2 Ã 8-Ge(1 1 1) surface, with a Curie temperature of about 300 K are investigated. Magneto-optical Kerr effect infers the existence of in-plane easy magnetization direction. We describe the epitaxial registry condition, the room temperature-zero field magnetic structure observed by magnetic force microscopy and the magneto-optical properties. The observations are consistent with the formation of epitaxial Mn5Ge3 alloy, with a modulated magnetic structure characterized by asymmetric 180° Bloch walls consisting of a vortex-like configuration of the local magnetization.
