Increase of Curie temperature of magnetic semiconductors by illumination
Afanas'ev M.M., Kompan M.E., Merkulov I.A.
Results are presented of an investigation of the influence of illumination on the magnetization of the domains in ferromagnetic europium sulfide (Tc = 16°K). It follows from the experimental results that illumination leads to an increase of the magnetization, a fact interpreted as an increase of the Curie temperature of EuS by an amount on the order of 10 '°K under the influence of the light.
