The Hall resistivity and magnetization have been investigated in the ferromagnetic state of the bilayered manganite La2−2xSr1+2xMn2O7 (x=0.36). The Hall resistivity shows an increase in both the ordinary and anomalous Hall coefficients at low temperatures below 50K, a region in which experimental evidence for the spin glass state has been found in a low magnetic field of 1mT. The origin of the ...

The electrical resistivity r of three-dimensional amorphous superconducting films a-Mo3Si and a-Nb3Ge is measured in magnetic fields m0H up to 30 T. At low temperatures and at magnetic fields above the upper critical field Hc2, r is temperature independent and decreases as a function of magnetic field. This field dependence is consistent with localization theory in the high-field limit @m0H@\/(...

the creep behavior of basalt fiber reinforced epoxy (bfre) and glass fiber reinforced epoxy (gfre) composites was studied through tensile testing at high temperature. to study the effect of reinforcing epoxy, the micro glass powder (mgp) was added at various volume percentage into the epoxy resin in bfre composites. the initial strain for all the specimens were evaluated and compared with each ...
