Description

Flux-tube nucleation rates have been measured in the current-induced resistive state of type I superconducting In films between 1.5 and 2.0 K by a completely passive technique. Indication of periodic nucleation is observed only in narrow regions of sample voltage drop, whose position is a sensitive function of temperature. Frequency bandwidth measurements of the nucleation rate yield a spectral purity of one part in 104 within the narrow regions where an experimental signal can be detected. (orig.)

Abstract (German)

Im strominduzierten Widerstandszustand von Typ I supraleitenden In-Filmen wurden Keimbildungsraten von Roehren mit magnetischem Fluss unter Verwendung einer voellig passiven Technik zwischen 1,5 und 2 K gemessen. Anzeichen fuer eine periodische Keimbildung wird nun in den engen Bereichen des Spannungsabfalles an der Probe beobachtet, dessen Lage empfindlich von der Temperatur abhaengt. Messungen der Frequenzbandbreite der Keimbildungsrate ergeben eine spektrale Reinheit von 1:104 innerhalb der engen Bereiche, in denen ein experimentelles Signal empfangen werden kann. (orig.)
