μSR studies of CePd2In at low temperatures

Abstract

Low-temperature properties of the heavy-fermion antiferromagnet CePd2In were investigated by muon-spin relaxation in zero external magnetic field (ZF- ). The time spectra below 1.2 K reveal the muon-spin oscillation characteristic of a magnetically ordered state with very small ordered Ce moments. Based on our data we discuss possible magnetic structures and compare them with the previous suggestions.
