Symko, Orest George | Characteristics of YBaCuO magnetic shields | Magnetic shielding properties of YBaCuO tubes have been studied at temperatures of 77 K and 4 K. Shielding effectiveness was determined by measuring the magnetic field inside the tube in the presence of external magnetic fields. A high degree of shielding was achieved up to a critical external fie... | YBaCuO magnetic shields; SQUID | 1991-03 |

Vardeny, Zeev Valentine; Symko, Orest George | Femtosecond dynamics of quasi-particles in YBa2Cu3O7-δ superconductor films | We have studied the transient electronic response of YBa2Cu307-δ epitaxialy grown H T c superconductor thin films in the femtosecond time domain, using transient photoinduced reflectivity (AR) with 60 fsec time resolution. For temperatures T>Tc only a bolometric signal was observed with ARrO. For ... | Femtosecond dynamics; YBa2Cu3O7-8; Transient electronic response; Transient optical response | 1991-03 |

Symko, Orest George; Vardeny, Zeev Valentine | Femtosecond dynamics of quasi-particles in YBa2Cu3O7-δ superconductor films | We have studied the transient electronic response of YBa2Cu30y . 5 epitaxialy grown HTC superconductor thin films in the femtosecond time domain, using transient photoinduced reflectivity (∆R) with 60 fsec time resolution. For temperatures T>TC only a bolometric signal was observed with ∆R>0. F... | Femtosecond dynamics; Superconductor films; YBCO films | 1991-03 |

Symko, Orest George | Multi-fluxon steps in long Josephson junctions and their application to oscillators | Studies of long NbN Josephson junctions of the overlap type in the presence of an external magnetic field show constant voltage steps, of the Fiske type, and large voltage steps. The latter are attributed to multifluxon resonances within the cavity of the junction. The multifluxon steps correspond t... | NbN; Multi-fluxon steps; Oscillators | 1991-03 |
