SPIN TRANSPORT IN MAGNETICALLY ORDERED SYSTEMS: EFFECT OF THE LATTICE RELAXATION TIME

- Angular dependence of the proton Zeeman spin- lattice relaxation rate in the various smectic phases of TBBA as obtained on cooling the sample from the

Whereas the second moment of the 1H resonance line is not appreciably sensi- tive to this phase transition, because no large amplitude motions are concerned, the

Fujuki and Betts [14], and also Nishimori and Nakan- ishi [15] discussed the disappearance of long-range or- der in the study of quantum spin systems on the trian-

For the compa- rison between theory and experiment, the time constant Tl of the exponential decay in the low- energy limit (that is at high temperature) will be

Spin-lattice relaxation time for a 3d5 ion in Td symmetry in the Raman region... SPIN-LATTICE RELAXATION TIME FOR A 3d5 ION IN Td

Abstract.- The nuclear spin-lattice relaxation times for 1 1 9 Sn and 117 Sn have been measured in the temperature range between 20 and 50 mK with a SQUID magnetometer by

We made a complete calculation for Sm3+ in a cubic environment and showed that this temperature dependence still holds for transitions between non Kramers conjugate
