The role of imperfections on magnetic and thermodynamic properties of cerium magnesium nitrate in the low-temperature magnetic phase transition region

Abstract

We present the measurement of the low-temperature properties of an imperfect crystal of the salt cerium magnesium nitrate and find that imperfections have a profound influence on the low-temperature behavior of the salt; in particular, (1) an anomalously high x'/ C is observed at very low temperatures, (2) there is a maximum in X' which enables one to explore the critical properties of the substance, and (3) there is an indication that relaxation times are decreased by the imperfections.
