$^{11}$ B NMR study of pure and lightly carbon doped MgB $_{2}$ superconductors

M. Karayanni, G. Papavassiliou, M. Pissas +5

We report a $^{11}$ B NMR line shape and spin-lattice relaxation rate ( $1/ (T_{1} T)$ ) study of pure and lightly carbon doped MgB $_{2 - x}$ C $_{x}$ for $x = 0$ , 0.02, and 0.04, in the vortex…

Surface barrier and bulk pinning in MgB $_{2}$ superconductor

M. Pissas, E. Moraitakis, D. Stamopoulos +3

We present a modified method of preparation of the new superconductor MgB $_{2}$ . The polycrystalline samples were characterized using x-ray and magnetic measurements. The surface bar…
