The field of ultrafast magnetism explores how flashes of light can manipulate a material's magnetization in trillionths of a second. In the process called all-optical switching (AOS), a single laser ...

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 ...

A single ultrashort laser pulse can change the magnetization of a suitable material. But even within a magnetic film of just a few nanometer ...

To magnetize an iron nail, one simply has to stroke its surface several times with a bar magnet. Yet, there is a much more unusual method: A team led by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) ...

Figure 2. Current-driven switching behaviors in MnSb 2 Te 4 at different temperatures and fields. (a) A schematic of the measurement procedure. (b) The magnetization process induced by dc pulses after ...

Research from the University of Minnesota Twin Cities gives new insight into a material that could make computer memory faster and more energy-efficient. The study was recently published in Advanced ...

An international research team has discovered the anomalous Hall effect in a collinear antiferromagnet. More strikingly, the anomalous Hall effect emerges from a non-Fermi liquid state, in which ...
