Nf. Kharchenko et al., REFLECTANCE MAGNETIC CIRCULAR-DICHROISM SPECTRA OF RE(2)CUO(4), Journal of magnetism and magnetic materials, 144, 1995, pp. 1281-1282
In reflectance magnetic circular dichroism spectra of RE(2)CuO(4) sing
le crystals the characteristic features were revealed in 1.5-4.5 eV. T
he band near 1.7 eV was inherent to each of the spectra, while UV band
energies changed with RE ion and depended on temperature similarly to
temperature behavior of magnetic susceptibility of corresponding crys
tal.
