Vortex avalanches at one thousandth the superconducting transition temperature.
We study the nonequilibrium dynamics of vortex motion at millikelvin temperatures in untwinned single crystals of YBa2Cu3O72d. Above threshold fields of many tesla, flux jumps appear in the magnetic hysteresis B(H). These jumps correspond to a change of 750 vortices, on average, under our micrometer-sized Bi Hall probes. Not only are the threshold fields large, but they, and the characteristics...
متن کاملThermal hysteresis in low-frequency noise of La0.7Sr0.3Mn0.92Fe0.08O3 thin films at low magnetic field
The low-frequency 1/f voltage noise of epitaxial La0.7Sr0.3Mn0.92Fe0.08O3 thin films has been studied as a function of temperature (80–300 K) and magnetic field (up to 1500 G). It is found that the noise power spectral density (PSD) shows a peak at T ≈ 238 K which coincides with the peak temperature of the resistivity, and is below the Curie temperature. When a small magnetic field of 1500 G is...
متن کاملHybrid superconducting nanostructures: very low temperature local probing and noise
We review the topic of hybrid superconducting nanostructures by introducing the basic physical concepts and describing recent key experimental results. We discuss the superconductivity nucleation in mesoscopic structures, the vortex lattice imaging in doped diamond films, the superconducting proximity effect, multiple Andreev reflection in Josephson junctions and the electronic micro-cooling in...
متن کاملDependence of the superconducting transition temperature on the doping level in single-crystalline diamond films.
Homoepitaxial diamond layers doped with boron in the 10(20)-10(21) cm(-3) range are shown to be type II superconductors with sharp transitions (approximately 0.2 K) at temperatures increasing from 0 to 2.1 K with boron contents. The critical concentration for the onset of superconductivity in those 001-oriented single-crystalline films is about 5-7 10(20) cm(-3). The H-T phase diagram has been ...
متن کاملPhotoinduced Changes in High Temperature Superconducting Films
Photoexcitation experiments performed in oxygen deficient but metallic YBa,Cu,O, c-axis oriented films revealed that the persistent photoinduced enhancement of conductivity and superconductivity are not restricted to the insulating side of the metal-insulator transition. A clear increase of the critical temperature T,, which is accompanied by a decrease of the resistivity in the normal state pa...
