ESR and Electron Spin Relaxation Time T1 of be Small Particles

  • Sanshiro Sako


The ESR spectra in the Be small particles (size 28Å~70Å) were investigated in the temperature range from 3K to room temperature at 9.1GHz and at room temperature at 35GHz, In any spectrum, the Curie-like paramagnetic component was, more or less, detected in addition to the Pauli paramagnetic one with the g value of 2.0033±0.0002. Those spin species are discussed. The size dependence of the spin relaxation time T1 was measured in the above temperature range. The increasing tendency of T1 with the decrease of size was observed. It is indicated from the experimental result of T1 that those spectra reflect the softening effect of lattice vibration or the quantum size effect.
