The Bi0.8Er0.1Ba0.1Fe0.96R0.02Cr0.02O3 (R = Mn3+ and Co2+) compounds were prepared by the Sol-Gel method and sintered at 800 °C for 2 hours. Both compounds present a rhombohedral structure with R3C space group. The nano-size criteria is confirmed for both compounds. The compound with Mn3+ ions presents the higher saturation magnetization and the higher amount of ferromagnetic contributions.
