Title:
Magnetic Phase Diagram of {{PrPb3}} Investigated by Specific Heat and Magnetocaloric Effect 
Abstract:
The intermetallic compound PrPb3 exhibits antiferroquadrupolar (AFQ) ordering at low temperature. We investigated the magnetic phase diagram through measurements of the specific heat and the magnetocaloric effect. In zero magnetic field the specific heat shows a second-order phase transition with an ordering temperature TAFQ=0.39K in line with earlier results. In addition, we find a further transition at T$∗$=0.35K for 3T and T$∗$=0.49K for 4.5T, which, however, is only observed upon heating. Th...    »
