Stress/Strain Induced Flux Pinning in Highly Dense Bulks

We have systematically studied the flux pinning behavior of MgB 2 bulks synthesized by direct diffusion of Mg into pressed pellets of high purity crystalline B powder, with and without mixing with C and SiC nanoparticles, at a reaction temperature of 850 deg C for 10 hrs. All of the samples showed v...
