Origin of large polarization in multiferroic YMnO3 thin films

Multiferroic materials have attracted much interest because of their ability to control magnetism through the application of a voltage. This ability can be utilized to reduce the power required by electronic devices and to ...

Magnetic switch gets closer to application

Scientists from Paris, Newcastle and Helmholtz-Zentrum Berlin have been able to switch on and off robust ferromagnetism close to room temperature by using low electric fields. Their results are inspiring for future applications ...

Probing spin liquids with a new pulsed-magnet system

Entirely new experimental vistas could be opened by a device called a precursor pulsed-magnet system developed by an international team of scientists. This system can generate magnetic fields as high as 30 Tesla for synchrotron ...

Making mini-magnets that induce a quantum anomalous Hall effect

A new device has been fabricated that can demonstrate the quantum anomalous Hall effect, in which tiny, discrete voltage steps are generated by an external magnetic field. This work may enable extremely low-power electronics, ...
