Very high upper critical fields in MgB2 produced by selective tuning of impurity scattering [PDF]

, 2003
We report a significant enhancement of the upper critical field $H_{c2}$ of different $MgB_2$ samples alloyed with nonmagnetic impurities. By studying films and bulk polycrystals with different resistivities $\rho$, we show a clear trend of $H_{c2 ...

Effects of weak anchoring on C1 and C2 chevron structures [PDF]

, 2005
We present a theoretical study of the effect of weak anchoring on the transition between C1 and C2 chevron structures in smectic C liquid crystals. We employ a continuum theory which allows for variable cone, azimuthal and layer tilt angles.
