Strain effect on the magnetic properties of BFMO films: a) Magnetic hysteresis (M – H) curves in the range of -5 ≤ H ≤ 5 kOe at RT with the field applied in the sample plane for Film2 (black square) and Film3 (red square). b) The relationship between c-axis lattice parameter (open squares), FWHM of ω-rocking curves (red squares) and film thickness. c) Normalized in-plane M – T curves of Film2 and Film3. The magnetic transition temperatures of Film2 and Film3 are > 600 K and ∼500 K, respectively. d) Schematic illustration for disordered BiFe_0.5Mn_0.5O₃ structure and various combinations of B-O-B(B′) bond.
