The kinetics of flux jumps in type II superconducting disks

Publikováno v: Journal of Low Temperature Physics. 16:119-124

Experimental studies of the kinetics of flux jumps in type II superconducting disks have shown that flux penetration into the specimen can be described by an exponential function of time. We present a phenomenological theory which uses the concepts o

THE ANALYTICAL INVESTIGATION OF EARLY BRONZE AGE JET AND JET-LIKE MATERIAL FROM THE DEVIZES MUSEUM

Autor: A. M. Pollard, G. D. Bussell, D. C. Baird

Publikováno v: Archaeometry. 23:139-167

Non destructive x-ray fluorescence analysis was used to discriminate between jet and similar materials (oil shales cannel coals); Comparison with previous neutron activation analysis made; Many British bronze age objects identified as jet, not shale

Dynamic resistance of the current-induced intermediate state in superconductors

Autor: H. D. Wiederick, B. K. Mukherjee, D. C. Baird

Publikováno v: Journal of Low Temperature Physics. 41:25-35

We have measured the in-phase component of the low-frequency ac impedance of the dc current-induced intermediate state in wires of pure and impure type I superconductors. We find that this dynamic resistance of the intermediate state is greater than

Kinetics of the current-induced phase transition in type I superconducting wires

Autor: D. C. Baird, H. D. Wiederick, B. K. Mukherjee

Publikováno v: Journal of Low Temperature Physics. 21:257-269

We have measured the time required for the destruction of type I superconductivity in high purity indium wires by a current greater than the critical current. Our results are not in agreement with theoretical treatments presented by Pippard and by Ro

Structure of the current-induced intermediate state in type I superconductors

Autor: B. K. Mukherjee, H. D. Wiederick, D. C. Baird

Publikováno v: Journal of Physics D: Applied Physics. 4:1365-1369

Several models have been proposed for the intermediate state which occurs when superconductivity is destroyed in type I wires by a current. Experimental testing of these models has, so far, only been possible through measurements of the resistance an

THE SUPERCONDUCTING TRANSITION IN POLYCRYSTALLINE TIN

Autor: R. A. Aziz, D. C. Baird

Publikováno v: Canadian Journal of Physics. 37:937-943

The influence of grain size on the breadth of the superconducting transition in polycrystalline tin has been studied. The transition has been detected using an a-c. induction method. A range of grain sizes from 0.2 mm to 10 mm was used and the corres
