SUSCEPTIBILITY AND PROTON LINE SHIFT OF ZR0.33NI0.67-H-X ALLOYS

The proton NMR line shift with respect to water, the bulk susceptibili ty and in a few cases the Korringa contribution to the spin lattice re laxation time were measured in Zr0.33Ni0.67-H-X amorphous alloys with hydrogen concentration 0.1 less than or equal to x less than or equal to 0.7 and at 343 K. All the parameters, including the hydrogen conten t and the bulk susceptibility, were measured simultaneously in situ, a nd in the shift measurements a resolution of +/-1 ppm was attained. Th e residual Knight shift depends on the hydrogen content and is positiv e relative to water. Preliminary low temperature spin lattice relaxati on time measurements indicate that the positive shift is the consequen ce of the balance of s- and d-contributions.
