The low-temperature proton spin–lattice relaxation is analysed for lanthanum hydrides
LaHx
intentionally doped with Gd or Ce. These paramagnetic impurities were also characterized
by static magnetic susceptibility and electron spin resonance measurements. A quantitative
description of the proton relaxation rate maxima, as well as of the electron spin relaxation
data, is presented. These analyses indicate that the density of states at the rare earth site
disappears only for .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
