Studies of Electron Spin Resonance (ESR) in TbMnO3 multiferroic compound

We report temperature dependent X-Band (v ~ 9.5 GHz) Electron Spin Resonance (ESR) measurements in a single crystal of TbMnO₃. The temperature dependence of this ESR linewidth was investigated in the three crystallographic orientations. The field-dependence of ESR line investigated by ESR experiments using other Band frequencies will be also discussed. TbMnO₃ is orthorhombic insulator of the multiferroic parents. In order to further investigate the magnetic properties we have performed ESR measurements in a single crystal of TbMnO₃ as function temperature and field.
