Abstract

The pinning by twin planes and an isotropic pinning disorder was investigated on single crystals of NdBa2Cu3O7-} and YBa₂Cu₃O_7-δ studying the angular dependence of total magnetic moment measured quasistatically by means of SQUID and dynamically by means of a vibrating sample magnetometer. The field dependence of the normalized relaxation rate of the vortex system pinned by twin planes, and by a random isotropic pinning disorder was determined. The qualitative difference of the two field profiles is clearly reflected by the shapes of the corresponding magnetic hysteresis loops. Material aspects of the pinning and the effect of the measurement method are discussed.
