Researchers at the University of Basel and the ETH in Zurich have succeeded in changing the polarity of a special ferromagnet using a laser beam. In the future, this method could be used to create ...

A single, ultrafast laser pulse has flipped the polarity of a ferromagnet without first heating it to the brink of losing its magnetism, pointing to a new way to write data at extreme speeds with far ...

Researchers at ETH Zurich and the University of Basel have inverted the direction of the magnetic field of a ferromagnet – comparable to a compass needle – using a short laser pulse. The ferromagnet ...

Here’s what you’ll learn when you read this story: The Earth’s magnetosphere protects life from deadly space radiation, but many aspects of its function remain a mystery. Scientists have long believed ...

Scientists have succeeded in changing the polarity of a special ferromagnet using a laser beam. In the future, this method could be used to create adaptable electronic circuits with light. (Nanowerk ...
