Reduced leakage current, enhanced ferroelectric and dielectric properties in Mn-doped BiFeO3 thin film composited with TiO2 layers

Evolution of the crystal structure and magnetic properties of Sm-doped BiFeO3 ceramics across the phase boundary region

“…Over the last decades, ferrites and manganites have attracted great attention of scientific society [1][2][3][4][5][6][7], especially the multiferroic BiFeO3 due to the complex interplay between the ferroic orders and the possibility to control the properties using various chemical doping schemes and synthesis methods [8][9][10][11][12]. Chemical doping can be used as an effective tool to neutralize the known drawbacks of the BiFeO3-based materialshigh leakage current, nullified remanent magnetization, low or canceled magnetoelectric coupling [13][14][15][16][17][18]. Chemical doping can also be used to induce metastable structural state observed for the compounds in the vicinity of the structural phase transitions and characterized by an increased sensitivity to the external stimuli as temperature, pressure, electric and magnetic field etc.…”
