dc.description.abstract |
The pulsed NMR method is applied to an analysis of a complicated structure of inhomogeneous internal fields in a ferromagnetic crystal. Proton magnetic resonance in the Ising ferromagnet TbES at a temperature range from 1.6 K down to 35 mK is studied at frequencies of 10-35 MHz. A complicated picture of static and fluctuating internal magnetic fields in the crystal is presented. Interatomic distances are shown to have an uncertainty of the order of 0.2% due to defects in the crystal lattice. The fluctuations of internal magnetic fields produced by thermal excitation and spin-spin relaxation of Tb3+ ions give rise to the effective nuclear magnetic relaxation: 1/T1(2)∼exp (δ/kT), where δ is the energy splitting of the lowest Tb3+ quasi-doublet. The rate of these fluctuations in TbES at low temperatures is approximately equal to 2×107 s-1 being independent of temperature and magnetic field. © 1990 Springer. |
