Direct observation of spontaneous weak ferromagnetism in the superconductor ErNi2B2C.

Neutron measurements show that superconducting ErNi2B2C (T(C) = 11 K) develops antiferromagnetic spin density wave magnetic order (T(N) = 6 K), which squares up with decreasing temperature yielding a series of higher-order magnetic Bragg peaks with odd harmonics. Below T(WFM) = 2.3 K where magnetization indicates a net moment develops, even-order Bragg peaks develop which low field (approximate...

دینامیک شار در ابررسانای Y3Ba5Cu8O18

We have studied the thermally activated flux creep of a newly fabricated superconductor Y3Ba5Cu8O18 with the superconducting transition temperature 102 K. Analysis of the transition spread from the normal state to superconducting state in the electrical resistivity revealed that the thermally activated flux creep explains the electron share in the vicinity of the transition temperature Tc. The ...

Effects of the sintering temperature on the flux-pinning mechanism and the activation energy of malic-acid doped MgB2

  The flux-pinning mechanism and activation energy of 10 wt % malic acid-doped MgB2 were investigated by measuring of the critical current density and resistivity as a function of magnetic field and temperature. A crossover field, Bsb, was observed from the single vortex to the small vortex bundle pinning regime. For the sintered sample, the temperature dependence of Bsb(T) at low temperature i...
