High-quality single crystals of Lu2Fe3Si5 and Sc2Fe3Si5 are grown by the floatingzone method, and their temperature dependences of specific heat are measured down to 0.35 K. Both compounds show anomalously small jump in specific heat at the superconducting transition temperature, Tc, and large residual specific heat coefficient even at 0.2Tc, where BCS superconductor shows negligible electronic...

Nonlinear transport in the low-temperature vortex glass state of single crystal Bi2Sr2CaCu2O8 has been investigated with fast current pulses driven along the ab plane. Field cooled preparation shows a higher threshold current ~marking a jump or break in slope in the voltage response! than the zero field cooled ~ZFC! one, but it is found to be metastable and convertible to the ZFC response by a ...

A “jump” in the blue horizontal-branch (HB) distribution in the V , u − y color-magnitude diagram has recently been detected in the globular cluster (GC) M13 (NGC 6205) by Grundahl, VandenBerg, & Andersen (1998). Such an effect is morphologically best characterized as a discontinuity in the u, u− y locus, with stars in the range 11,500 K . Teff . 20,000 K deviating systematically from (in the s...

Introduction. When a fiber-reinforced viscoelastic material is cooled from cure temperature to room temperature the different coefficients of thermal expansion of the matrix and fibers lead to residual stresses. To study this phenomenon in detail, we consider a thin, isotropic, thermorheologically simple, linearly viscoelastic plate reinforced by a random system of fibers lying in the plane of ...

The solutions of a renormalized BCS model are studied in two space dimensions in s, p and d waves for finite-range separable potentials. The gap parameter, the critical temperature Tc, the coherence length ξ and the jump in specific heat at Tc as a function of zero-temperature condensation energy exhibit universal scalings. In the weak-coupling limit, the present model yields a small ξ and larg...

The paper addresses the properties of glassforming melts in an attempt to predict the dependence of viscosity on temperature and on pressure. A review on the main viscosity models (free volume model, the Adam & Gibbs model etc.) is given. It is demonstrated that the activation energy can be expressed through the glass transition temperature Tg. The main attention is concentrated on the jump fre...
