Mechanism 'splits' electron spins in magnetic material

Holding the right material at the right angle, Cornell researchers have discovered a strategy to switch the magnetization in thin layers of a ferromagnet—a technique that could eventually lead to the development of more ...

Visualizing spin angular momentum in water waves

Water waves can be used to visualize fundamental concepts, such as spin angular momentum, that arise in relativistic field theory, RIKEN physicists have shown. This will help to provide new insights into very different wave ...

Controlling the speed of magnetic devices

In an international collaboration led by scientists from the Fritz Haber Institute in Berlin, a novel approach to controlling the speed of magnetic processes has been developed.

Using the principle of coherent feedback to cool a quantum system

We've all experienced the principle of feedback—for example, when we use a thermostat in conjunction with a heating system to regulate indoor temperature. The thermostat measures the current temperature, compares it with ...
