Physicists achieved a robust and reliable magnetization switching process by domain wall displacement without any applied fields. The effect is observed in tiny asymmetric permalloy rings and may pave ...

Magnetic domains can take on a wide range of structures. In certain soft magnetic materials, they form complex zig-zag patterns known as maze domains. These patterns change in complicated ways as ...

This process is repeated several times, whereby the time interval between the first "pump" pulse and the subsequent "probe" pulse is continually extended. As a result, a time series of reflection data ...

Engineers at Rice University in the U.S. have developed a new room-temperature multiferroic material ...

MRAM (Magnetoresistive Random-Access Memory) is a type of non-volatile memory (NVM) that utilizes magnetic states to store information. The basic structure of MRAM is a magnetic-tunnel junction (MTJ), ...
