Magnetic phase control by an electric field

Article Abstract:

A system whose magnetic phase can be controlled by an external field, ferromagnetic ordering in hexagonal HoMnO3 is reversibly switched on and off by the applied field through magnetoelectric interactions is reported. The basic requirements for other candidate materials to exhibit magnetoelectric phase control are identified.

Current-induced resonance and mass determination of a single magnetic domain wall

Article Abstract:

A magnetic domain wall (DW) is a spatially localized change of magnetization configuration in a magnet. The direct observation of the dynamics of a single domain wall (DW) in a ferromagnetic nanowire is reported, which demonstrates that such a topological particle has a very small but finite mass of 6.6 * 10 (super -23) kg.

Spintronics gets a magnetic flute

Article Abstract:

A new class of electronic device based on a spin-transfer switch for magnetic-memory 'spintronics' is described. The spin-transfer mechanism in response to magnetic and electric field is explained.
