Abstract
A high-resolution Bitter decoration technique has been used to observe the microstructure of flux-line lattices in melt-processed YBa2Cu3Oy (YBCO). In particular, we studied both static and dynamic flux distributions at low ( 4-23 K) and high temperatures (68-69 K) after field-cooling in the presence of 150 G. We could observe the flux motion after a long deposition time. T here were remarkable differences in the behaviour of the flux motion, depen ding on the temperature.
