Two-magnon bound state causes ultrafast thermally induced magnetisation switching
(Nature Publishing Group, 2013-11)
There has been much interest recently in the discovery of thermally induced magnetisation switching using femtosecond laser excitation, where a ferrimagnetic system can be switched deterministically without an applied ...
