An experimental investigation on Raman scattering from magnons and phonons has been made for FeBO 3 . A Raman line at 537 cm -1 is confirmed as due to two-magnon excitations from a comparison of the spectra of pure FeBO 3 crystals with In-substituted

Contraction motions of stripe domains in an as-grown LPE-garnet film are studied by a time-resolved observation method. Most of the contraction motions are grouped into three types based on the shapes of the stripe ends. In the smaller driving force

Photoconductivity and photoluminescence spectra of undoped and Cr-doped samples of CdIn 2 S 4 have been measured. Ligand-field-induced photoconductivity and photoluminescence have been observed in the Cr-doped sample. A mechanism of the photoconducti

Contraction motions of stripe domains in several types of hard bubble suppressed LPE-garnet films are studied by a time-resolved observation technique. Saturation velocities observed are substantially larger than those observed in collapse and transl

Annealing behavior of magnetic anisotropy in LPE garnet films are investigated. There exists a good correlation between the activation energy for the decreasing process of K u and the difference between the ionic radii of the constituent rare earth i

The first-order Raman spectra of trigonal Se and Te have been measured under pressure up to the semiconductor-metal transition points at room temperature. In both materials, a prominent pressure effect is found as an anomalous shift of the A 1 mode t

The magnetic properties and cation distributions of ferrite-chromite series of nickle and cobalt are investigated. Although the magnetic moments at absolute zero temperature are well explained by simple Neel model as far as the series remain inverse

The optical absorption spectra of HgCr 2 Se 4 single crystals in the intrinsic transition region were measured as a function of magnetic field at a number of fixed temperatures. The absorption edge, 0.80 eV, at room temperature shifted to 0.27 eV at

Distributions of the quadrupole splitting observed by the Mossbauer effect in amorphous YFe 2 and Fe 16 Ni 62 B 14 Si 8 broaden during annealing below their crystallization temperatures. From the broadening it is concluded that the structural relaxat

Magnetic circular polarization effects on the phonon Raman scattering of CdCr 2 S 4 are investigated in the Faraday configuration. Anomalous intensity differences of spin-dependent phonon lines are observed between two spectra with different circular
