Almeida-Thouless Line in BiFeO3: Is Bismuth Ferrite a mean field spin glass?
Manoj K. Singh, Ram S. Katiyar, W. Prellier +1
Low-temperature magnetic properties of epitaxial BiFeO3 thin films grown on (111)-SrTiO3 substrates have been studied. ZFC and FC magnetization curves show a large discrepency begi…
The beta Phase of Multiferroic Bismuth Ferrite and its beta-gamma Metal-Insulator Transition
R. Palai, R. S. Katiyar, H. Schmid +5
We show that epitaxial (001) thin films of multiferroic bismuth ferrite BiFeO3 are monoclinic at room temperature instead of tetragonal or Rhombohedral as reported earlier . We rep…
Giant sharp magnetoelectric switching in multiferroic epitaxial La_{0.67}Sr_{0.33}MnO_3 on BaTiO_3
W. Eerenstein, M. Wiora, J. L. Prieto +2
Magnetoelectric coupling permits a magnetic order parameter to be addressed electrically or vice versa, and could find use in data storage, field sensors and actuators. Coupling co…
