Multiferroic nature of charge-ordered rare earth manganites
Claudy Rayan Serrao, A Sundaresan, C N R Rao
Charge-ordered rare earth manganites Nd0.5Ca0.5MnO3, La0.25Nd0.25Ca0.5MnO3, Pr0.7Ca0.3MnO3 and Pr0.6Ca0.4MnO3 are found to exhibit dielectric constant anomalies around the charge-o…
Ferromagnetism as a universal feature of nanoparticles of the otherwise nonmagnetic oxides
A. Sundaresan, R. Bhargavi, N. Rangarajan +2
Room-temperature ferromagnetism has been observed in the nanoparticles (7 - 30 nm dia) of nonmagnetic oxides such as CeO2, Al2O3, ZnO, In2O3 and SnO2. The saturated magnetic moment…
Room-temperature ferromagnetism in nanoparticles of superconducting materials
Shipra, A. Gomathi, A. Sundaresan +1
Nanoparticles of superconducting YBa2Cu3O7-delta (YBCO) (Tc = 91 K) exhibit ferromagnetism at room temperature while the bulk YBCO, obtained by heating the nanoparticles at high te…
Realization of biferroic properties in La0.6Sr0.4MnO3 0.7Pb(Mg0.33Nb0.67)O3 0.3(PbTiO3) epitaxial superlattices
Ayan Roy Chaudhuri, r. Ranjith, S. B. Krupanidhi +4
A set of symmetric and asymmetric superlattices with ferromagnetic La0.6Sr0.4MnO3 and ferroelectric 0.7Pb(Mg0.33Nb0.67)O3 0.3(PbTiO3) as the constituting layers were fabricated on…
