Anomalous paramagnetic effects in the mixed state of LuNi2 B2 C
Abstract
Anomalous paramagnetic effects in dc magnetization were observed in the mixed state of LuNi2B2C , unlike any reported previously. It appears as a kink-like feature for H⩾30kOe and becomes more prominent with increasing field. A specific heat anomaly at the corresponding temperature suggests that the magnetization anomaly is due to a true bulk transition. A magnetic flux transition from a square to an hexagonal lattice is consistent with the anomaly.
