In a collaboration between the Universities of Manchester and Exeter a new article has been published today in Scientific Reports. Lead by Dr Craig Barton at the University of Manchester we investigated the role of strain in FeRh layers on MgO.
FeRh goes from antiferromagnetic to ferromagnetic in bulk at around 70°C. However, in thin films this temperature can change depending on the thickness and the material it is interfaced with. In this new article we measured the effect of film thickness on the transition temperature and correlated the effects with changes in the structural properties. We corroborate a number of observations using theoretical models that account for the strain at the interface. The article is open access so anyone can download and read the article here.
