Abstract
We report on investigations of the magnetic properties of the tetravalent praseodymium (Pr4+) compound Sr2PrO4 by dc and ac magnetic susceptibility and heat capacity measurements. The compound shows signatures of long range magnetic order at T-N = 3 K in the heat capacity and magnetization data. In addition, the temperature dependence of the field cooled and the zero-field cooled susceptibility is hysteretic below 10 K. Heat capacity versus temperature data show that a significant part of the magnetic entropy is released above T-N. This reveals that short range magnetic correlations among the Pr moments exist well above T-N. The magnetic entropy obtained from the heat capacity measurements indicates that only the crystal field ground state of Pr with effective spin-1/2 is significantly populated at low temperatures.
