ISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: A compact, low-energy electron source for use at cryogenic temperatures is described. The device uses quartz optical fibers and a discharge lamp to excite photoelectrons from a cold zinc emitter. Picoampere currents are obtained with low heating. The source has been used in studies of surface-state electrons on liquid helium.Type of Medium: Electronic ResourceURL: -

ISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: A method is presented to measure the absolute value of the London penetration depth, λ(T=0), from the frequency shift of a resonator. The technique involves coating a high-Tc superconductor with film of low-Tc material of known thickness and penetration depth. The method is applied to obtain λ(YBa2Cu3O7−δ)(approximate)1460±150 Å, λ(Bi2Sr2CaCu2O8+δ)(approximate)2690±150 Å and λ(Pr1.85Ce0.15CuO4−δ)(approximate)2790±150 Å. λ(YBa2Cu3O7−δ) from this method is very close to that obtained by several other techniques. For both Bi2Sr2CaCu2O8+δ and Pr1.85Ce0.15CuO4−δ the values exceed those obtained by other methods. © 2000 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-7357Source: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract We present a review of our pulsed NMR experiments in the A and B phases of superfluid3He, at pressures of 23 and 27 bar. We have measured the dipole frequency in3He-A, spin susceptibility in3He-B, and tip-angle-dependent frequency shifts in both phases. In general, we find excellent agreement with results by other workers. In3He-B, complex spin motions were observed involving long-lived free induction decays with a time-dependent precession frequency. Spin relaxation measurements for both3He-A and3He-B are discussed and compared with those of other workers. After driving the magnetization far from equilibrium, anomalous frequency shifts were found to persist in the A phase. We discuss a soliton-texture model by Bruinsma and Maki which accounts for these resonances.Type of Medium: Electronic ResourceURL:
