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.
EnglishMagneto-resistive measurements at microwave frequencies have been carried out in c-oriented Bi2Sr2CaCu2O8+x films. When the angle curly theta between the magnetic-field direction and the (a, b)-plane is varied a large anisotropy is observed in the microwave absorption. In the range 4-degrees < curly theta less-than-or-equal-to 90-degrees, the dissipation scales as H sin curly theta, but below 4-degrees an anomalous enhancement of dissipation is present. The behaviour of the enhancement is measured as a function of the temperature in the range (70 divided-by 85) K.

| Abstract: | Magneto-resistive measurements at microwave frequencies have been carried out in c-oriented Bi2Sr2CaCu2O8+x films. When the angle curly theta between the magnetic-field direction and the (a, b)-plane is varied a large anisotropy is observed in the microwave absorption. In the range 4-degrees < curly theta less-than-or-equal-to 90-degrees, the dissipation scales as H sin curly theta, but below 4-degrees an anomalous enhancement of dissipation is present. The behaviour of the enhancement is measured as a function of the temperature in the range (70 divided-by 85) K. |
