Outline of Final Research Achievements

The magnetoelectric effect (electric/magnetic stimulus generates magnetic/electric response) in bulk matter is of growing interest both fundamentally and technologically. This effect has been studied intensively in multiferroic materials. We have discovered a new class of bulk magnetoelectric phenomenon, which is fundamentally distinct from that in multiferroic materials. We have demonstrated experimentally that in elemental tellurium, bulk magnetization is induced parallel to an applied current, which is quite beyond classical electromagnetism and the current framework for magnetoelectricity in multiferroic materials.
