Abstract
We report results of a dc magnetic and ac linear low-frequency study of a polycrystalline MgB2 sample. AC susceptibility measurements at low frequencies, performed under dc fields parallel to the sample surface, provide clear evidence for surface superconducting states in a polycrystalline MgB2.
