Gk. Perkins et al., THE EFFECT OF TWIN PLANE BOUNDARIES ON THE VORTEX DYNAMICS IN TWINNEDYBCO CRYSTALS, Physica. C, Superconductivity, 282, 1997, pp. 2149-2150
Using a transverse field vibrating sample magnetometer in which the sa
mple may be rotated with respect to the applied field, we have made ma
gnetisation measurements of twinned YBCO crystals over a wide range of
angle. We examine the influence of the vortex to twin boundary intera
ction on the vortex dynamics.
