Popis:	The frozen magnetoresistance of ceramic Bi(Pb)-HTSC samples is investigated as a function of the fields initiating magnetic flux trapping and the magnetization-reversing fields: Rt(Hi,Hr). It is found that the Rt(Hr) curves are nonmonotonic. The value of the frozen magnetoresistance decreases substantially after application of the first Hr pulse (Hr
