Magneto-oscillations in dislocation drag at low temperatures

Experimental results are presented which show how dislocation drag varies with an applied magnetic field. We find that the dislocation drag varies roughly as H 2 in high-purity zinc single crystals. This field dependence agrees with previous measurements on Cu and Al Furthermore, we find magneto-oscillations in the dislocation drag process superimposed on the variation of δ[sgrave] with H in zinc single crystals.
