Hydrogen ordering influence on the proton spin-lattice relaxation time in metal-hydrogen compoun Hydrogen ordering influence on the proton spin-lattice relaxation time in metal-hydrogen compounds

TL;DR

This paper investigates how hydrogen ordering affects proton spin-lattice relaxation times in metal-hydrogen compounds, providing experimental evidence for order-order transformations in lanthanum hydrides.

Contribution

It presents experimental results indicating hydrogen ordering influences relaxation times and confirms order-order transformations in LaH2+c hydrides.

Findings

Hydrogen ordering impacts proton relaxation times.

Order-order transformations occur in LaH2+c hydrides.

Experimental data supports the existence of phase transformations.

Abstract

Results of the experimental study of ordering lanthanum hydrides of LaHX system are presented. It is shown that obtained results can be interpreted as an indirect confirmation of the existence of order-order transformations in LaH2+c hydrides.
