Synthesis and multiferroic properties of particulate composites resulting from combined size effects of the magnetic and ferroelectric phases Abstract: The effect of grain size was not fully explored in composites containing ferroelectric and magnetic phases […]
Ferroelectricity in the 1 μC cm−2 range induced by canted antiferromagnetism in (LaMn3)Mn4O12 Abstract: Pyroelectric current and field-dependent specific heat measurements on polycrystalline samples of the quadruple perovskite (LaMn3)Mn4O12 give evidence of ferroelectricity driven by the canted antiferromagnetic […]
Electrical properties of calcium doped BiFeO3 films on LaNiO3 coated Pt substrates Abstract: Pure and calcium-modified (CaxBi1-xFeO3, x = 0.0, 0.1, 0.2, 0.30) thin films were fabricated on Pt(111)/Ti/SiO2/Si substrates by the soft chemical method using […]
Intense photoluminescence emission at room temperature in calcium copper titanate powders Abstract: We report the structural and magnetic properties of Co2MnO4, partially substituted by Bi at the octahedral site. Bismuth enhances ferromagnetism due to a decrease […]
Intrinsic magnetic properties of BixCo2−xMnO4 spinels obtained by short-time etching Abstract: We report the structural and magnetic properties of Co2MnO4, partially substituted by Bi at the octahedral site. Bismuth enhances ferromagnetism due to a decrease of the […]
