To study the mechaniam of grain boundary flux pinning and estimate the elementary pinning force per unit length, f/sub pL/, niobium bicrystals were used as a model system. The principal advantage of bicrystals is they allow a single selected grain boundary to be studied, which eliminates the complications of a statistical summation in evaluating f/sub pL/.
