Anomalous thickness-dependent strain states and strain-tunable magnetization in Zn-doped ferrite epitaxial films

A series of ZnxFe3−xO4 (ZFO, x = 0.4) thin films were epitaxially deposited on single-crystal (001)-SrTiO3 (STO) substrates by radio frequency magnetron sputtering. The anomalous thickness-dependent strain states of ZFO films were found, i.e., a tensile in-plane strain exists in the thinner ZFO film...
