We report on the structural and magnetic properties of CoFe2O4 films under epitaxial strain. The films are grown with high structural quality on MgO, SrTiO3, and piezoelectric Pb(Mg1/3Nb2/3)0.72Ti0.28O3 substrates by pulsed laser deposition. The substrate-induced strain is found effective to alter the magnetic anisotropy of the films. Reversible strain measurements using the piezoelectric substrates are providing evidence that nearly bulk-like magnetoelastic properties are maintained for films of down to at least 25nm thickness. This is in contrast to unsubstituted cobalt ferrite films and suggests that a chemical control of the spinel lattice provides a promising route to optimize the tunability of the magnetic properties of thin ferrite films.
