National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Abstract Heat capacities of LaIn3, CeIn3 and PrIn3 have been measured between 7 and 300K. The LaIn3 results fit a Debye curve with Theta = 170K. PrIn3 has a Schottky-type anomaly around 36K, from which an overall crystal field splitting of about 170K is derived with the singlet Gamma(1) as the lowest state. The heat capacity and magnetic behavior of PrIn3 indicate a value of the crystal field parameter chi in the range -0.8 to -0.6. CeIn3 shows a Schottky anomaly around 60K, which yields a crystal field splitting of 155K (doublet lowest). A lambda-type anomaly is observed at 10.4 plus or minus 0.5K, the Neel point. The magnetic entropy indicates that the doublet Gamma(7) is the lowest level in CeIn3. The sign of the crystal field splitting is in both compounds in agreement with point charge predictions.
