Weak Localization Correction to Linear Absorption in Conventional Superconductors

Weak localization in superconductors: A study of radiation-damaged Nb3Ir.

Weak-localization correction to the anomalous Hall effect in polycrystalline fe films.

In situ transport measurements have been made on ultrathin (<100 A thick) polycrystalline Fe films as a function of temperature and magnetic field for a wide range of disorder strengths. For sheet resistances Rxx less than approximately 3kOmega, we find a logarithmic temperature dependence of the anomalous Hall conductivity sigmaxy, which is shown for the first time to be due to a universal sca...

Nonbackscattering Contribution to Weak Localization

We show that the enhancement of backscattering responsible for the weak localization is accompanied by reduction of the scattering in other directions. A simple quasiclassical interpretation of this phenomenon is presented in terms of a small change in the effective differential cross-section for a single impurity. The reduction of the scattering at the arbitrary angles leads to the decrease of...

Paramagnetic Meissner Eeect in Conventional Nb Superconductors

The paramagnetic Meissner eeect (PME), in which the eld-cooled-magnetization (FCM) of superconducting samples is positive below the super-conducting transition temperature T c , has been observed in certain ceramic and single-crystal samples of the high-T c cuprate superconductors and more recently in disk-shaped Nb samples. Through systematic investigations of the conditions for observing the ...

Probing Anderson localization of light by weak non-linear effects

Breakdown of wave transport due to strong disorder is a universal phenomenon known as Anderson localization (AL). It occurs because of the macroscopic population of reciprocal multiple scattering paths, which in three dimensional systems happens at a critical scattering strength. Intensities on these random loops should thus be highly increased relative to those of a diffusive sample. In order ...
