Density-of-states fluctuation-induced negative out-of-plane magnetoresistance in overdoped Bi-2212
We analyzed the in-plane and out-of-plane magnetoresistance (MR) for
overdoped BiPbSrCaCuO (Bi-2212) single
crystals using superconductive fluctuation theory, which considers the
density-of-states (DOS) contribution in layered superconductors with the
conventional s-wave pairing state. The out-of-plane results are well reproduced
by the theory, implying that the large, negative out-of-plane MR as well as the
sharp increase in the zero-field out-of-plane resistivity near the
superconducting transition temperature originate from the superconductive
DOS fluctuation effect. On the other hand, the in-plane results are better
reproduced without the DOS contribution (i.e., using only the Aslamazov-Larkin
(AL) contribution), which may be explained in terms of the d-wave
superconductivity of the layered superconductors.Comment: 4 pages, 3 figures, 27th International Symposium on
