Complex bulk oxides, including perovskites and double perovskites structures, conform a rich scenario to study different physics properties and also to design new materials as multiferroic composites. In particular, we focus our attentionin to study double perovskites with Sr/Ba-Fe-Mo-O compositions that present coexistence of itinerant and localized electrons. On the other hand, other studied system, as double perovskites with Sr/Ba-Mn-Mo-O, shows insulators and ferrimagnetism behaviors. While, R-Fe-Cr/Co-O (where R is rare earth) perovskites present complex magnetic behaviors as magnetic frustration, spin reorientation mechanisms and clues of multiferroic behavior. We will show a brief conclusions about the advance of our studies in the bulk magnetic and in the design of new multiferroic materials.
