Abstract
We present a compared experimental investigation of the (a, b) plane vortex-state complex resistivity at 48 GHz in YBa2Cu3O7-delta, SmBa2Cu3O7-delta and Bi2Sr2CaCu2O8+x, In YBa2Cu3O7-delta and SmBa2Cu3O7-delta the field dependence of the response can be consistently by contrast, described by a combination of flux flow and strong pair breaking due to the presence of lines of nodes in the gap. In Bi2Sr2CaCu2O8+x the data might be described by the pair breaking alone. (c) 2005 Elsevier Ltd.
