Flux dynamics and irreversibility in YBa{sub 2}Cu{sub 3}O{sub 7} with Y{sub 2}BaCuO{sub 5} inclusions and in single crystal YBa{sub 2}Cu{sub 3}O{sub 7}
Abstract
We have measured the ac magnetic permeability response function {mu} = {mu}{prime} + i{mu}{double_prime} in melt-processed melt grown YBa{sub 2}Cu{sub 3}O{sub 7} with Y{sub 2}BaCuO{sub 5} inclusions (MPMG) and in single crystal YBa{sub 2}Cu{sub 3}O{sub 7} (SC) in applied magnetic fields up to 8 Tesla oriented either parallel or perpendicular to the crystalline c-axis. The ac response of the two samples has been mapped out as a function of temperature, frequency, ac field amplitude, dc applied field, and field orientation. The peak in the lossy part of the susceptibility {mu}{double_prime} is used to probe the flux dynamics in the vicinity of the irreversibility line. The data are interpreted by comparison with expectations of an anisotropic vortex glass- to -liquid transition. The inferred melting lines as well as the frequency dependence and non-linear response are in overall agreement with the expected behavior. In the range of available parameters and variables we find the system to be in the solid vortex phase for H{perpendicular}c since there is a strong H{sub ac} dependence and only a weak frequency dependence on the temperature position of the loss peak. For H{parallel}c, the situation is reversed, and the loss peak depends only weakly on H{sub ac}more »
