We report temperature dependent X-Band (f~9.5 GHz) Electron Spin Resonance (ESR) and microwave absorption measurements in a single crystal of TbMnO3. A single Lorentzian ESR line with an isotropic g-value g~1.96 was observed for Tges120 K up to 600 K. The ESR signal is attributed to the Mn3+ ions in a insulator environment. The temperature dependence of the ESR linewidth is investigated for the external field applied along the three crystallographic axes. For all direction the ESR linewidth… CONTINUE READING
