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 p...
