The conductivity and photoconductivity of undoped single crystals of the ferromagnetic semiconductor HgCr2Se4(Tc=106K) were studied between 50K and 300K. Both dependences exhibit a deep minimum near Tc and a metallic-like behaviour at low temperature

New direct experimental evidences for a magnetic-order-induced band splitting were found in the spectral dependence of the photoconductance in the ferromagnetic semiconductor CdCr 2 Se 4 . The strong asymmetry of the “red” and “blue” shifts o

Diffuse reflectance, diffuse thermoreflectance (DTR), and specular thermoreflectance (TR) of the ferromagnetic semiconductor CdCr2Se4 are measured in the region of photon energies from 1.2 to 3.3 eV, between 95 and 320 °K. The TR spectra clearly sho
