Magnetic control of ferroelectric polarization

Nature, 2003
The 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).

WEST Magnetic Control

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 ...

Magnetic Control and Real-Time Monitoring of Stem Cell Differentiation by the Ligand Nanoassembly.

Small, 2021
Native extracellular matrix (ECM) exhibits dynamic change in the ligand position. Herein, the ECM-emulating control and real-time monitoring of stem cell differentiation are demonstrated by ligand nanoassembly. The density of gold nanoassembly presenting
