“…However, a decrease in magnetic properties is evident when increasing the CMO content from 5% to 10% at room temperature. Similar behavior was reported with the addition of LaMn 0.5 Co 0.5 O 3 to BFO thin films [45]. Interestingly, the influence of CMO addition on magnetization becomes more pronounced at low temperatures.…”

The effect of ferromagnetic CaMnO3 (CMO) addition to structural, magnetic, dielectric, and ferroelectric properties of BiFeO3 is presented. X-ray diffraction and Raman investigation allowed the identification of a single pseudocubic perovskite structure. The magnetic measurement showed that the prepared films exhibit a ferromagnetic behavior at a low temperature with both coercive field and remnant magnetization increased with increasing CMO content. However, a deterioration of magnetization was observed at room temperature. Ferroelectric study revealed an antiferroelectric-like behavior with a pinched P–E hysteresis loop for 5% CMO doping BFO, resulting in low remnant polarization and double hysteresis loops. Whereas, high remnant polarization and coercive field with a likely square hysteresis loop are obtained for 10% CMO addition. Furthermore, a bipolar resistive switching behavior with a threshold voltage of about 1.8 V is observed for high doped film that can be linked to the ferroelectric polarization switching.

“…Noting that the simultaneous presence of Mn 3+ , Co 3+ and Fe 3+ is not always a sufficient condition to improve magnetization at room temperature. Recently we have shown that in the BFO-LaMn0.5Co0.5O3 system, the simultaneously presence of Mn 3+ and Co 3+ in the Fe-sites doesn't improve the magnetization of BFO at room temperature [35], because the result structural edifice do not permit the magnetic interactions to be active. In addition, the Raman investigation undertaken for BGFMCo sample highlight the existence of JT distortion induced by the presence of Mn 3+ which is still active similarly to the mother matrix.…”

In this work we elaborated and characterized nanocomposite thin films using a preselected multiferroic matrix Bi0.9Gd0.1Fe0.9Mn0.1O3 (BGFMO) in the aim to enhance their basic ferroelectric and magnetic properties. The local ferroelectric character of these nanocomposites thin films was investigated by piezoresponse force microscopy (PFM). Switching behavior for ferroelectric domains was probed by locally manipulating domains. The magnetic investigation showed that the incorporation of transition metal elements in the BGFMO matrix brings out interesting increase in the macroscopic magnetisation at room temperature. Moreover, a spin glass type behavior is observed in M(T) curves for the studied thin films.
