✦ Synopsis

Intercalation

by benzene had a dramatic effect on room-temperature DC magnetization curves of high-T, Bi-oxides. In contrast to weak paramagnetism (XZ 10e6 emu/g per Gauss) of the initial samples, the intercalated samples exhibited an enhanced hysteretic magnetism with a complex field dependence. It is characterized by a steep rise at low fields, a broad maximum around 0.25 T, and a steady decline at higher fields up to 5.5 T, with magnetization becoming negative above 1.2 T. Hysteresis values were apparently field-independent within the studied range of 0 to 5.5 T. Tentative models are proposed to explain the observed anomalous magnetization.
