Abstract
Microwave absorptions were measured on a-oriented YBa2Cu3Ox, thin film for three magnetic field (H-a) directions along a-, b-, and c-axis with various sweep rates. The signal for H(a)parallel toc is largest at low field and d ecreases fastest with increasing H-a in middle field range. While, the sign al for H(a)parallel tob is smallest at the low field and decreases most gra dually. This signal for H(a)parallel toc increases most rapidly with increa sing the sweep rate. Anisotropic vortex properties and vortex dynamics are discussed. (C) 2001 Elsevier Science B.V. All rights reserved.
