  <dc:description>In the present study, the linear behavior of the second harmonic signal generated by application of very low DC magnetic fields to the polycrystalline bulk high-T (c) superconductors has been examined. The amplitude of AC field, H (ac) , intergranular first critical field, H (1cJ) , and minimum field required for the magnetization of specimen as a whole, H (au), were determined and a special coil design has been presented. The results reveal that the second harmonic signal varies linearly with the applied DC field in the -0.1 Oe to 0.1 Oe range. Additionally, detection of ultra-low DC fields as small as 5 nT has been achieved. Repeatability and reproducibility tests were performed and the resultant data have been found to be consistent. In the light of our study, a commercial magnetometer can be produced to be utilized in successful detection of very low magnetic fields.</dc:description>
