Ov. Miloslavskaya et al., MAGNETOOPTICALLY DETECTED ELECTRIC-DIPOLE ALLOWED ELECTRON TRANSITIONS IN THE R(3+) IONS IN R(2)CUO(4) (R=PR, ND, SM, EU AND GD), Czechoslovak journal of Physics, 46, 1996, pp. 2671-2672
The reflectance magnetic circular dichroism (RMCD) spectra of the R(2)
CuO4 crystals (R=Pr, Nd, Sm, Eu and Gd) were studied in the visible l
ight (1.5-4.5 eV) at the temperatures from 10 to 260 K in the magnetic
held up to 65 kOe. The nature of observed electric-dipole allowed tra
nsitions in R fe ions is supposed to be 4f(n)-4f(n-1) 5d one.
