Moon spin relaxation has been used to study the implantation and dynamics of muons in the proton conductor HZr2(PO4)(3) as a function of temperature. Muons are implanted at two different sites. One can be identified as H(2)Omu(+) on the basis of its low temperature second moment, Deltaomega(0)(2). The other site is less well defined, Deltaomega(0)(2) suggests P-O-mu with an associated hydrogen. Dynamic averaging of the nuclear field is observed for H(2)Omu(+) above ca. 160 K, whereas no dynamic processes are observed for the P-O-mu below 400 K. Above 400 K, further averaging of the nuclear field of both sites takes place which is attributed to translational diffusion of the union through the lattice. (C) 2003 Elsevier B.V.
