NMR; line shape; spin-lattice relaxation

The NMR probe and the matching network has been designed for the¹H NMR study in CeNiInH_0.53 down to liquid helium temperature using Bruker MSL 100 spectrometer. NMR line-shape measurement shows the absence of any signature of proton pairing in CeNiInH_0.53 down to 3.86 K, as it was observed for high hydrogen concentration. The measurement of the spin-lattice relaxation time in the temperature range 300–20K reveals that the relaxation rate is mainly governed by the Korringa-type relaxation mechanism.
