MAGNETIC AND NUCLEAR-RESONANCE PROPERTIES OF SINGLE-CRYSTAL SCANDIUM

Magnetic-susceptibility, magnetic-anisotropy, and nuclear-magnetic-resonance measurements were performed on single-crystal scandium samples from 4.2 to 300°K. The susceptibility of single-crystal scandium is greater along the a axis than along the c axis. The nuclear relaxation rate (T1T)-1 has a sin2θ dependence on the angle between the static magnetic field and the crystallographic c axis. The orbital hyperfine interaction is the major contribution to the relaxation rate. From the experimental results, values are estimated for the electronic density of states, the average fractional s character, the average fractional admixture coefficients for d electrons at the Fermi surface, and the orbital paramagnetism. © 1969 The American Physical Society.
