Abstract: We report temperature dependent X-Band (ν ∼ 9.4 GHz) electron spin resonance (ESR) measurement in a single crystal of TbMnO3. A single Lorentzian ESR line with an isotropic g ∼ 1.96 was observed for T ≥ 120 K up to 600 K. The ESR signal is attributed to the Mn3 + ions in a insulator environment. For the three crystallographic axes the temperature dependence ESR linewidth shows a strong broadening as the temperature decreases due to the presence of short range magnetic correlations. © 2006 Elsevier B.V.
