Onset of superconductivity at 107K in YBa2Cu3O7 - δ at high pressure

Electrical resistivity ρ measurements under pressure have been carried out on the high-temperature superconductor YBa2Cu3O7 - δ as a function of temperature T between 1 and 300 K at various pressures between 8 kbar and 149 kbar. The superconducting transition temperature Tc increases almost linearly with pressure at the rate dTc/dP ∼- 0.13 K/kbar. The onset of Tc, defined as the temperature at which ρ(T) drops to 90% of its extrapolated normal state value, increases from ∼95 K at 8 kbar to 107 K at 149 kbar. These results suggest that higher pressures will yield yet higher values of Tc. © 1988 Springer-Verlag

Magnetoresistance of UBe13 at high pressures

We have measured the temperature dependence of the electrical resistivity of UBe for magnetic fields up to 8 T and pressures to 95 kbar. Pressure increases the temperature range over which ρ{variant} = ρ{variant} + AT , while the pressure and magnetic field dependences of ρ{variant} and A reflect changes in the quasiparticle interactions. © 1990. 13 0 0

STRUCTURE OF THE HEAVY-FERMION SUPERCONDUCTOR UBE13

Voting for radical right-wing parties has been associated most strongly with national identity threats. In Europe, this has been framed by the radical right in terms of mass-migration and European integration, or other politicians bargaining away national interests. Perhaps surprisingly given the radical right’s nationalist ideology, nationalistic attitudes are hardly included in empirical research on the voting behaviour. In this contribution, we test to what extent various dimensions of nationalistic attitudes affect radical right voting, next to the earlier and new assessed effects of perceived ethnic threat, social distance to Muslims, Euroscepticism and political distrust. The findings show that national identification, national pride and an ethnic conception of nationhood are additional explanations of radical right voting. National identification’s effect on radical right voting is found to be stronger when populations on average perceive stronger ethnic threat

Elastic neutron scattering in UCd11

We report results of neutron powder diffraction experiments on the heavy-electron magnet UCd at temperatures above and below its ordering temperature. These measurements set an upper limit on the ordered moment of 1.5μ /U. © 1988. 11

Scaling of the magnetoresistance of UBe13 under pressure

We report magnetoresistance measurements of the heavy electron compound UBe above the superconducting transition temperature T and below 4 K for pressures P up to 19 kbar and for magnetic fields H up to 9 T. We observe strong negative magnetoresistance at all pressures and temperatures. The resistivity ρ is quadratic in temperature T from T up to a maximum temperature of 1 K at 1 bar increasing to 2 K at 19 kbar. The slope of the T term decreases with both H and with P. We find that δ(H)≡-[ρ(H)-ρ(0)]/ρ(0) for a given pressure scales as a function of H/T and exhibits power-law behavior over one decade with an exponent of 1.7. In addition, δ(H) at high pressure shows this same power law over a more limited H/T range. 13 c c
