Calculation of Spin Relaxation Rate of Iron Ion
Journal Title: Bulletin of Pure and Applied Sciences Sec. D – Physics - Year 2018, Vol 37, Issue 2
Abstract
The present paper discusses the spin relaxation process and calculates the spin relaxation rate of Iron ion (Fe+3). We also have discussed the variation of the spin relaxation rate with different low temperature and from this result, it has been shown that at low temperature this mechanism is in-effective in the temperature range up to 300K. We have extended this work to apply the temperature range up to 500K and showed that the relaxation rate at low temperature, relaxation rate at low temperature due to Hamiltonian doublet and relaxation rate at low temperature using strain operator increase with increasing the temperature. This also concludes that indirect two phonon process cannot be dominant mechanism for spin relaxation of S-state Iron ions and not able to produce any observable effect on the Mossbauer hyperfine spectrum.
