Abstract

We report highly resistive strongly ferromagnetic strained thin (∼30 nm) films of BiFe_0.5 Mn_0.5 O₃ (BFMO) grown on (001) SrTiO₃ substrates using pulsed laser deposition. The films are tetragonal with high epitaxial quality and phase-purity. The magnetic moment and coercivity values at room temperature are 90 emu/cc (0.58 _μB /B -site ion) at H=3 kOe and 274 Oe, respectively. The magnetic transition temperature is strongly enhanced up to ∼600 K, which is ∼500 K higher than for pure bulk BiMnO₃. Strained BFMO is a potential room temperature spin filter material for magnetic tunnel devices.
