TEMPERATURE AND FREQUENCY DEPENDENCES OF NMR SPIN-LATTICE RELAXATION TIME T1 IN a-Si : H

- 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

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

agree with the results of a theoretical calculation of the temperature dependence of the spin exchange frequency shift cross-section and with an experimental result

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 presented a theoretical kinetic model which takes into account the existence of two kinds of site for hydrogen in the amorphous network: one site is a center from which

Xhen samples are annealed, the increase in the ESR center density is remarkable in a-Si:F:H and a-Si:H corresponding to the decrease in the H content, but the increase in

In the high-temperature substrate film of lower hydrogen content which we employed for this study, we see no evidence for either significant low temperature (T<300°C)
