In magnetic alloys, the effect of finite temperature magnetic excitations on phase stability below the Curie temperature is poorly investigated, although many systems undergo phase transitions in this temperature range. We consider random Ni-rich Fe-Ni alloys, which undergo chemical order-disorder transition approximately 100 K below their Curie(More)
Aknowledgements First of all, I would like to thank to my thesis supervisors Héléna Zapolsky and Denis Ledue for accepting my candidature for this thesis and sharing their scientific experience. In particular, I would like to thank Héléna Zapolsky for giving me an introduction to the phenomena of phase transformations and for the valuable discussions during(More)
