| dc.description | The authors present the polarized far-infrared and Raman spectra of Bi<sub>2</sub>CuO<sub>4</sub> single crystals at 300 and 10 K in the spectral range from 30 to 650 cm<sup>-1</sup>. All infrared-active modes (10E<sub>u</sub>+5A<sub>2u</sub>) as well as 21 Raman-active modes were observed. At low temperatures, for x'y' and x'z polarizations, new structure appears which the authors assigned as a two-magnon mode. The assignment of the observed vibrational modes is given according to Cartesian symmetry coordinates and a preliminary force constant calculation on the basis of a rigid-ion model. |
