Modeling huge photoinduced spin polarons in intrinsic magnetic semiconductors
S. C. P. van Kooten, X. Gratens, A. B. Henriques
In intrinsic magnetic semiconductors, the absorption of a single photon can generate a spin polaron, whose magnetic moment reaches many thousands of Bohr magnetons [1.2]. Here we i…
Hypergiant spin polarons photogenerated in ferromagnetic europium chalcogenides
X. Gratens, Yunbo Ou, J. Moodera +2
We find that in the ferromagnetic semiconductor EuS, near its Curie temperature, a single band-edge photon generates a spin polaron (SP), whose magnetic moment approaches 20,000 Bo…
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…
