Proton magnetic resonance absorption spectra of yttrium dihydride (YH2+x), with x=0.10, were recorded in the temperature ranges 4.2–310 K at 36.01 MHz and 150–400 K at 299.8 MHz. The evidence of proton self-diffusion follows from the changes of l

We report on the first observation of the 89Y NMR signal in the hexagonal trideuteride phase YD2.98 at 14.7 MHz (7.04 T) and 302 K. In this phase the 89Y nuclei are in an environment characterized by the shift tensor components δiso=361, δ aniso =9

Proton nuclear magnetic resonance absorption spectra and spin-lattice relaxation rates in yttrium dihydride have been measured in the temperature range from 4.2 to 310K at 36.0MHz. The second moment of the resonance line corresponds to the rigid-latt

2H NMR spectra and spin-lattice relaxation rates, R1 are measured as functions of temperature (4.2-310 K) for YD1.99 and YD1.99+0.04. In YD1.99 the measured temperature dependence of R1 is explained by the interaction of deuteron spins with conductio

We have derived a closed-form expression for the solid echo signal of quadrupolar I = 1 nuclei after the pulse sequence (theta1)x-tau-(theta2)y-t for arbitrary values of the RF nutation frequency omega1 = gammaB1 and the quadrupolar frequency omegaQ.

Nuclear magnetic resonance of 53 Cr in ferromagnetic CrBr 3 in external magnetic fields was studied at 4.2 K. In zero field, a well-resolved NMR triplet (at 54.434 ± 0.297 MHz) was observed from domains, a single resonance (54.86 MHz) from domain wa

Expressions are derived for the initial relaxation rate 1/T1 of protons and deuterons of nontunnelling NH4 and ND4 groups reorienting about various symmetry axes in solids. The reorientation rates are modified by a trigonal, tetragonal or monoclinic

The spin-lattice relaxation time T1 and the NMR absorption line shape of deuterons in ND4ReO4 were measured in the temperature range from 46 to 294 K. The T1 versus T curve shows a single minimum and gives the activation energy of 10.5 kJ/mol for the

The 139 La nuclear magnetic resonance of lanthanum hydrides in LaH 2+ x ( x = 0.32, 0.38, 0.40, 0.74) was measured over the temperature range 2.3 to 303 K. A single, temperature-dependent line width was found in LaH 2.74 above 250 K, whereas a comple
