Abstract

We present the results of ac susceptibility and microwave studies of polycrystalline MgB₂. The frequency dependence of the ac susceptibility indicates that there is a strong intergranular pinning potential (8 eV) for the vortices. The microwave results are explained in terms of resistively shunted Josephson junctions within the sample. The field dependence of the microwave absorption also indicates that the intergranular pinning is strong in this material.
