Benvenuti nell'Anagrafe della Ricerca d'Ateneo
La valutazione delle attività di ricerca che si svolgono nelle università ha assunto un'importanza rilevante sia per l'intero sistema universitario sia all'interno di ogni singolo ateneo. Roma Tre si è quindi dotata di idonei strumenti informativi in grado di supportare al meglio le azioni di monitoraggio e di valutazione delle attività di ricerca svolte nei propri dipartimentied ha realizzato una Anagrafe della Ricerca di Ateneo.
EnglishWe consider the field dependence of the microwave resistivity in high-T-c superconductors. We present field-dependent microwave resistivity measurements at 48 GHz on thin YBa2Cu3O7-delta and Bi2Sr2CaCu2O8+x films. The field dependence of the microwave resistivity cannot be satisfactorily described in terms of a single model for the flux motion when both materials are considered. We introduce and discuss a simple model that incorporates the effect of the enhanced field-induced quasiparticle increase in a superconductor with Lines of nodes in the gap, together with viscous flux motion. A good description of the data is obtained, for YBa2Cu3O7-delta as well as for Bi2Sr2CaCu2O8+x.

| Abstract: | We consider the field dependence of the microwave resistivity in high-T-c superconductors. We present field-dependent microwave resistivity measurements at 48 GHz on thin YBa2Cu3O7-delta and Bi2Sr2CaCu2O8+x films. The field dependence of the microwave resistivity cannot be satisfactorily described in terms of a single model for the flux motion when both materials are considered. We introduce and discuss a simple model that incorporates the effect of the enhanced field-induced quasiparticle increase in a superconductor with Lines of nodes in the gap, together with viscous flux motion. A good description of the data is obtained, for YBa2Cu3O7-delta as well as for Bi2Sr2CaCu2O8+x. | |
