Strong room temperature magnetism in highly resistive strained thin films of BiFe0.5Mn0.5O3
We report highly resistive strongly ferromagnetic strained thin (∼30 nm) films of BiFe0.5Mn0.5O3 (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...

| description | We report highly resistive strongly ferromagnetic strained thin (∼30 nm) films of BiFe0.5Mn0.5O3 (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 (0.58μB/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. |
