Knight shift and quadrupole interaction in single crystal magnesium Dougan, Patrick Daniel
The nuclear magnetic resonance in single crystal magnesium has been studied at 4.2°K. The isotropic Knight shift, the anisotropic Knight shift and the quadrupole interaction have been investigated. The values for the parameters measured are K = (0.1127 ± 0.0005)%, K' = (0.0004 ± 0.0002)%, e²qQ/h = 324 ± 6 KHz. These results are compared with those of Rowland in powdered magnesium to reveal the Knight shift is independent of temperature. This contrasts directly with the behavior of cadmium. The quadrupole interaction is shown to increase by 40% as temperature is lowered to 4.2°K from room temperature.
