The AC response of a type II superconducting Pb-8.4 at.%Na single-crystal cylindrical rod with a (111) orientation in the mixed state is described and analysed when the specimen is in the surface pinning regime. The results show that flux entry is no

We have studied nonlinear dissipation in oscillatory flow of3He-A through 49-µm- and 17-µm-wide channels by means of torsion pendulum experiments at about 50 Hz. The observed effects are strongly history dependent; the dissipation at a given measur

The normal-fluid viscosity of liquid $^{3}\mathrm{He}$-$B$ has been determined in the neighborhood of the superfluid transition using the torsional-oscillator technique of Andronikashvili. In the pressure range from 11.90 to 19.64 bars and for reduce

The response to an AC magnetic field of a type II superconducting single-crystal Pb-Na cylindrical rod has been observed as a function of longitudinal DC fields. The results show two different regimes of flux pinning within the specimen. At low field

The authors have used a torsion pendulum to measure the superfluid density and viscosity of liquid 3He at pressures of 18.2, 26.0 and 29.7 bar. It was found that rho s in the A-phase is not reproducible; the range of variation is about a factor of tw

Measurements of carrier lifetime have been made on both n- and p-type silicon crystals over the temperature range 0°C to 200°C. Results are given for both high and low values of injected carrier concentrations. A comparison is made with the Shockle

The recombination and generation processes for electrons and holes in an n-type semiconductor with acceptor traps are described when the concentrations of electrons and holes are much smaller than 1019 cm-3 at room temperature. With this assumption B

A set of small‐area, alloy, p‐n junction diodes was made from a slice of heat‐treated n‐type silicon. The carrier lifetimes of the diodes were found to be in the range of 2.5×10−8 sec to 3.5×10−6 sec. Measurements were made of the lifet
