What is Observation of anomalously long relaxation phenomena in Pb3BiSx thin films under pulsed magnetic field about?
We report the observation of very long relaxation time under pulsed magnetic fields of 0.15-1.3 kG for the Pb3BiS x thin Ž . films x s 2.0-3.0 biased at a certain current at liquid helium temperatures below 4.2 K. Both the superconducting Ž . Ž . x s 2.0, 2.5, 2.7 and nonsuperconducting x s 3.0 films exhibit the novel phenomena. They develop with reducing bath temperature below 4.2 K. The response time to a pulsed magnetic field ranges from a few seconds to a few tens of seconds much greater than those expected from the conventional microscopic lifetimes in the solid. The observed pulse shape is quite asymmetric, and the rise time is longer than the fall time. It strongly depends on the amplitude of magnetic field, but it weakly depends on the sulfur concentration x. The discussion is given in connection with the possible formation of quasilocal states of charge carriers separated from the band states by a barrier. q 1998 Elsevier Science B.V.
