  The optical absorption and luminescence spectra of antiferromagnetic spinel ZnCr 2 O 4 have been measured at temperature K. The data have been interpreted in frames of crystal field theory. Several sharp lines in absorption and emission have been attributed to Cited by: 8. A fine structure of the optical absorption spectrum of antiferromagnetic NaMnCl3 was measured around cm–1 at temperatures in the range –50 K in magnetic fields up to kOe.

Abstract A fine structure of the optical absorption spectrum of antiferromagnetic NaMnCl 3 was measured around cm −1 at temperatures in the range –50 K in magnetic fields up to kOe.

  The optical absorption spectrum of NiF 2 is reported for the paramagnetic and antiferromagnetic states. A prominent satellite appears in the 3 A 2 → 1 E transition below the Néel temperature. This new line is explained in terms of the interaction of the excited Ni 2+ ion with its six antiparallel Ni 2+ neighbors. The new magneto-optical effects, for the first time, provide means to distinguish visually between collinear, degree, or time-reversed antiferromagnetic (AFM) domains. The infrared reflection and absorption spectra of antiferromagnetic semiconductor MnTe 2 were measured in the energy range 33 cm -1 ∼ cm -1, and four optical phonon bands were observed near cm -1, cm -1, cm -1, and cm   The optical absorption spectrum of NiF2 is reported for the paramagnetic and antiferromagnetic states.

  Optical absorption (OA) spectrum and electronic structure of the hexagonal YMnO 3 compound have been investigated by employment of the first-principles calculations based on density functional theory. The calculations were performed upon the ferroelectric structure of the YMnO 3, by testing various approximations of the exchange-correlation effects between the Mn d-electrons and .   Consequently, this type of optical transition can hardly give rise to intense absorption bands as were observed in both the experimental and calculated optical absorption spectra shown in Fig. 4. In any event, if d 3 d charge-transfer transitions between the t 2 g states of the CO 3 + ion and t 2 g states of the CO 2 + ion exist, they must be. The optical pump-probe technique using ultrashort laser pulses with a photon energy of eV was used to study the dynamics of the antiferromagnet-paramagnet phase transition in FeBO3. Abstract. Optical absorption spectra of KNiF 3 and NiO stoichiometric single-crystals were measured at 5 K in the range from to cmThe observed bands are interpreted based on the energy levels diagram for Ni 2+ (3d 8) ion in a cubic crystal crystal-field parameter Dq is equal to cm-1 in KNiF 3 and cm-1 in NiO. Particular attention is paid to the band due to the.
