The improvement of ferromagnetic properties is critical for the practical application of multiferroic materials, to be exact, BiFeO3 (BFO). Herein, we have investigated the evolution in the structure and morphology of Ho or/and Mn-doped thin films and the related diversification in ferromagnetic behavior. BFO, Bi0.95Ho0.05FeO3 (BHFO), BiFe0.95Mn0.05O3 (BFMO) and Bi0.95Ho0.05Fe0.95Mn0.05O3 (BHFMO) thin films are synthesized via the conventional sol-gel method. Density, size and phase structure are crucial to optimize the ferromagnetic properties. Specifically, under the applied magnetic field of 10 kOe, BHFO and BFMO thin films can produce obvious magnetic properties during magnetization and, additionally, doping with Ho and Mn (BHFMO) can achieve better magnetic properties. This enhancement is attributed to the lattice distortions caused by the ionic sizes difference between the doping agent and the host, the generation of the new exchange interactions and the inhibition of the antiferromagnetic spiral modulated spin structure. This study provides key insights of understanding the tunable ferromagnetic properties of co-doped BFO.

Pure phase Mn-doped Na0.5Bi0.5TiO3 crystals were successfully synthesized by a hydrothermal method. Magnetic loops measured at room temperature indicate that ferromagnetism can be obtained in Mn-doped Na0.5Bi0.5TiO3 crystals, and the magnetism of Na0.5Bi0.5TiO3 crystals can be controlled by adjusting Mn doping concentration. The magnetism of the Mn-doped Na0.5Bi0.5TiO3 crystals varied from diamagnetism, ferromagnetism, and paramagnetic on increasing Mn doping concentration from 0 to 30mol%. The results showed in this study may provide an approach to widely exploring more multiferroic materials.
