2019 IEEE 58th Conference on Decision and Control (CDC), 2019
The WEST facility is an upgrade of the former Tore Supra tokamak. Two in-vessel coils have been added to elongate the plasma shape and achieve diverted magnetic configuration with one or two X-points. This modification has implied the design of a new plasma control system with a dedicated magnetic control to deal with the vertical instability of the ...

Magnetically Controlled Variable Logic
IBM Journal of Research and Development, 1964Magnetically controlled multipurpose logic provides a great flexibility and compactness. A matrix consisting of 2n saturable magnetic elements for n variable inputs is controlled by an adjacent magnetic pattern recorded on a magnetic medium, which determines the logical function to be performed.

Magnetic control of continuum devices
The International Journal of Robotics Research, 2017In this paper we apply Cosserat rod theory to catheters with permanent magnetic components that are subject to spatially varying magnetic fields. The resulting model formulation captures the magnetically coupled catheter behavior and provides numerical solutions for rod equilibrium configurations in real-time.

Magnetic control of ferroelectric interfaces
Journal of Physics: Condensed Matter, 2011We report the strong magnetic field dependence of ferroelectric PbZr(0.52)Ti(0.48)O(3) (PZT) films on half-metallic oxide La(0.67)Sr(0.33)MnO(3) (LSMO) electrodes. As the field H is increased, the hysteresis loop first broadens (becomes lossy) and then disappears at approximately H = 0.34 T and ambient temperatures.

Control of magnetism by electric fields
Nature Nanotechnology, 2015The electrical manipulation of magnetism and magnetic properties has been achieved across a number of different material systems. For example, applying an electric field to a ferromagnetic material through an insulator alters its charge-carrier population. In the case of thin films of ferromagnetic semiconductors, this change in carrier density in turn

Instruments and Experimental Techniques, 2012
A clamp for creating the thermal contact in vacuum between components of the cryostat on its preliminary cooling is described. The contact is established when heating conduits are pressed towards one another by a permanent magnet and is broken (established) when current pulses of appropriate polarity are applied to the winding around the iron magnetic ...

A Proton Magnetic Field Controller
Review of Scientific Instruments, 1972We have designed, constructed, and operated a magnetic field controller that locks the field to a proton nuclear magnetic resonance signal. The frequency of the proton spectrometer is, in turn, locked to a frequency swept synthesizer. The controller operates over ±1000 Oe centered at 3000 Oe. The long term stability is 3×10−3 Oe.

Magnetic control of ferroelectric polarization
Nature, 2003The magnetoelectric effect--the induction of magnetization by means of an electric field and induction of polarization by means of a magnetic field--was first presumed to exist by Pierre Curie, and subsequently attracted a great deal of interest in the 1960s and 1970s (refs 2-4).
