... Field dependent thermal conductivity of Tl 2 Ba 2 CuO 6 : evidence for Andreev scattering of quasiparticles. Abstract: . We have studied the thermal conductivity of Tl 2 Ba 2 CuO 6 (Tl-2201) crystals as functions of temperature and magnetic field. A thermal conductivity peak is observed near 0.6 T c which is greatly reduced on application of a magnetic field along the c axis. ... A model based on Andreev reflection by vortex screening currents is shown to be consistent with these results. ...

Cherechukin A.A., Koledov V.V., Shavrov V.G., Tulaikova A.A., Vasil'ev A.N. Magnetic and structural phase transitions in Ni2+УMn1-УGa (0<У<1) alloys are investigated experimentally. The martensite domains formation under the action of external magnetic field on the surface of polycrystalline Ni2,19Mn0,81Ga specimen was investigated by optical method. ... It is found that the martensite phase formation temperature is enhanced by the order of 0,3 K in magnetic field of 1 kOe. ...

... Measurements of magnetic fields on scales larger than galaxy clusters are needed to distinguish between fields generated in the primordial Universe and those generated at later epochs, with implications for particle physics, cosmology, and astrophysics. ... In this talk I will review mechanisms for generating magnetic fields across cosmic time, implications for post-recombination physics, and current observational constraints on intergalactic magnetic fields. ...

Abstract -- The strengths of magnetic fields in interstellar gas clouds are obtained through observations of the circular polarization of spectral line radiation. ... To infer information about these irregularities from the observational data, we develop statistical relationships between the rms values of the irregular component of the magnetic field and spatial variations in the circular polarization of the spectral line radiation. ...
