µSR and Muon Knight Shift Measurements on LaNi5Hx
Using the positive muon as a proton substitute, we have made spin relaxation and Knight shift measurements for three series of samples, which had undergone up to 40 hydrogenation cycles : LaNi5H6, LaNi5, and LaNi5 annealed. This enables us to separate the influence of hydrogen absorption on the muon Knight shift (+80 ppm) from the effect of Ni precipitations formed at the surface and from possible muon trapping at lattice defects.
