Abstract

Abstract: An investigation of the structural, magnetic and electronic properties of ≈3nm thick Mn5Ge3 films epitaxially grown on a Ge(1 1 1)-c(2×8) reconstructed surface is reported. High resolution transmission electron microscopy and selected area electron diffraction give evidence of 2.2% in-plane compressive strain between the Mn5Ge3 film and the Ge substrate. Magnetooptical Kerr effect measurements show that the films are ferromagnetic with a Curie temperature of ≈325K. The analysis of Ge 3d core level photoelectron spectra of the Mn5Ge3 films allows determining an upper limit of 76meV for the Ge 3d 5/2 core-hole lifetime broadening. The Ge 3d 3/2 core-hole lifetime broadening is found to be 15meV larger than that of the Ge 3d 5/2 core hole, because of the existence of a Coster–Kronig decay channel due to the metallic character of Mn5Ge3.
