Electric control of magnetism in a multiferroic metal-organic framework

Electric control of magnetism is demonstrated in a multiferroic metal-organic framework with a perovskite structure. A moderate electric field of a few kV/cm applied during the cooling process is able to cause a large (more than 50%) change of the magnetization at low temperature. This significant magnetoelectric effect is ascribed to the electric field manipulation of orientation of hydrogen bonds that modify the superexchange interaction between metal ions.
