摘要：
The magnetic response of HTSC Ba-K-Bi-O single crystals in superconducting state was investigated with the help of a small Hall detector. The magnetic moment of the sample was measured as a function of the magnetic field up to 650 Oe and as a function of temperature while heating in the external magnetic field. Distinct paramagnetic response (PMR) was observed. In contrast to the other works where "paramagnetic Meissner effect" was noted these experiments were carried out on zero field cooled samples and the paramagnetic response was exhibited both at very low (< 1 Oe) and while increasing to relatively high values of magnetic field.
