Electric-field control of domain wall nucleation and pinning in a metallic ferromagnet [PDF]

, 2013
The electric (E) field control of magnetic properties opens the prospects of an alternative to magnetic field or electric current activation to control magnetization. Multilayers with perpendicular magnetic anisotropy (PMA) have proven to be particularly

Electrically controlled magnetism

SPIE Proceedings, 2008
Manipulation of magnetically ordered states by electrical means is a promising approach towards novel spintronics devices. We report on the electric control of surface magnetism in Cr2O3 thin films and uniaxial anisotropy in ferroelectric/ferromagnetic heterostructures, respectively.

Magnetic control of particle-injection in plasma based accelerators [PDF]

, 2011
The use of an external transverse magnetic field to trigger and to control electron self-injection in laser- and particle-beam driven wakefield accelerators is examined analytically and through full-scale particle-in-cell simulations.

Optimal Magnetic Attitude Control

IFAC Proceedings Volumes, 1999
Magnetic torquing is attractive as means of control for small satellites. The actuation principle is to use the interaction between the earth's magnetic field and a magnetic field generated by a coil set in the satellite. This control principle is inherently time-varying, and difficult to use because control torques can only be generated perpendicular ...
