Probing individual edge states with unprecedented precision

A new technique makes it possible to obtain an individual fingerprint of the current-carrying edge states occurring in novel materials such as topological insulators or 2-D materials. Physicists of the University of Basel ...

Zero field switching (ZFS) effect in a nanomagnetic device

An unexpected phenomenon known as zero field switching (ZFS) could lead to smaller, lower-power memory and computing devices than presently possible. The image shows a layering of platinum (Pt), tungsten (W), and a cobalt-iron-boron ...

Piezomagnetic material changes magnetic properties when stretched

Piezoelectric materials, which generate an electric current when compressed or stretched, are familiar and widely used: think of lighters that spark when you press a switch, but also microphones, sensors, motors and all kinds ...

Spin current from heat—new material increases efficiency

Electronic devices such as computers generate heat that mostly goes to waste. Physicists at Bielefeld University have found a way to use this energy: They apply the heat to generate magnetic signals known as 'spin currents." ...

Spin currents switch at terahertz frequencies

The technology of spintronics is based on the intrinsic spin of electrons. In the medium term, it is set to replace electronics as the basis for technical devices. DESY scientist Lars Bocklage has discovered a new way of ...

Quantum theory for manipulating nanomagnets

Researchers at the Department of Physics, University of Jyväskylä, Finland, have created a theory that predicts the properties of nanomagnets manipulated with electric currents. This theory is useful for future quantum ...
