Stress Dependence of the Needle-Shaped Electron Pockets in Zinc

Abstract

The stress dependence of the cross-sectional area of the needle-shaped electron pockets in zinc was determined by magnetostriction techniques in which length changes were measured using a three-terminal capacitance method. Magnetization data were obtained by employing a torque balance. The stress coefficients of the needle pockets are $\frac{\partial \ln S_m}{\partial \sigma \mathrm{}\left[0001\right]\mathrm{}}=-(6.\mathrm{}0\pm 0.2)\times {10}^{-10\mathrm{}}$ ${\left({\mathrm{d}\mathrm{y}\mathrm{n}/\mathrm{c}\mathrm{m}}^2\right)}^{-1\mathrm{}}$, $\frac{\partial \ln S_m}{\partial \sigma \left[10\mathrm{}\overline{1}0\right]}=+(2.\mathrm{}4\pm 0.2)\times {10}^{-10\mathrm{}}$ ${\left({\mathrm{d}\mathrm{y}\mathrm{n}/\mathrm{c}\mathrm{m}}^2\right)}^{-1\mathrm{}}$, $\frac{\partial \ln S_m}{\partial \sigma \left[11\mathrm{}\overline{2}0\right]}=+(2.\mathrm{}5\pm 0.2)\times {10}^{-10\mathrm{}}$ ${\left({\mathrm{d}\mathrm{y}\mathrm{n}/\mathrm{c}\mathrm{m}}^2\right)}^{-1\mathrm{}}$.
