The heat capacity and magnetization of praseodymium metal in the temperature region 1.2-4.2°K with applied magnetic fields up to 40,000 G
The magnetic and thermal properties of two spherical samples of Praseodymium have been determined over the temperature region 1.2-4.2°K in magnetic fields to 40 kG. The zero applied magnetic field heat capacity data indicate the existence of an anomaly centered about 3.4°K and an upturn below 1.4°K. The temperature of the small 3.4°K anomaly decreases as the field is increased. The temperature of the onset of the upturn, as well as its magnitude, increases as the magnetic field is applied. This behavior was exhibited by both samples; however, the absolute magnitude of the heat capacity differed between samples. The magnetization exhibited no unusual behavior at 3.4°K; however, the magnetic moment in a 5000 G applied field increased as the temperature decreased. A remnant moment was detected in one of the samples after the application of a magnetic field. The effect of impurities on the anomaly is discussed.
