摘要：

The results of polarized micro-Raman scattering experiments on YBa2Fe3O8+delta with delta = 0.1 are reported. We identified seven out of the total ten by symmetry Raman-allowed phonons at 134 cm-1 (A1g), 148 cm-1 (E(g)), 219 cm-1 (A1g), 300 cm-1 (B1g), 478 cm-1 (A1g), 493 cm-1 (E(g)), and 691 cm-1 (A1g). The Raman-active phonons are assigned to definite atomic vibrations in close comparison with the structurally similar YBa2Cu3O6, Using simple considerations based on charge and bond length.
