Room-temperature spin glass behavior in zinc ferrite epitaxial thin films

Julia Lumetzberger, Verena Ney, Anna Zhakarova +3

Zinc ferrite (ZnFe${}_{\text{2}}$O${}_{\text{4}}$) epitaxial thin films were grown by reactive magnetron sputtering on MgAl${}_{\text{2}}$O${}_{\text{4}}$ and Al${}_{\text{2}}$O${}_{\text{3}}$…
