Converting Faraday rotation into magnetization in europium chalcogenides
S. C. P. van Kooten, P. A. Usachev, X. Gratens +4
We present a simple semiclassical model to sustain that in europium chalcogenides (EuX), Faraday rotation (FR) in the transparency gap is proportional to the magnetization of the s…

Ultrafast light switching of ferromagnetism in EuSe
A. B. Henriques, X. Gratens, P. A. Usachev +2
We demonstrate that light resonant with the bandgap forces the antiferromagnetic semiconducor EuSe to enter ferromagnetic alignment in the picosecond time scale. A photon generates…
