Thermal stability of epitaxial Mn5Ge3 and carbon-doped Mn5Ge3 films
A Spiesser, V Le Thanh, S Bertaina… - Applied Physics …, 2011 - pubs.aip.org
The thermal stability of epitaxial Mn5Ge3 and carbon-doped Mn5Ge3 films was investigated
by combining structural and magnetic characterizations. It is shown that ferromagnetic
Mn5Ge3 films transform into antiferromagnetic Mn11Ge8 upon post-annealing at 650 C
whereas carbon-doped Mn5Ge3 conserves its ferromagnetism up to 850 C. The magnetic
properties of Mn5Ge3 (Curie temperature, magnetization at saturation, and magnetic
moment per Mn atom) are found to undergo a reversible transition upon carbon doping and …
