Low temperature properties of a new Kondo Lattice compound Yb2Ir3Sn5
Abstract
We report the preparation and results of our magnetic and transport measurements on a new Yb-based ternary compound Yb2Ir3Sn5. This compound forms in the orthorhombic Cmc21 structure. DC magnetic susceptibility between 1.8 K and 300 K reveal that Yb is in its magnetic trivalent state in this compound. Electrical resistivity measurements down to 1. 5K show a behavior typical of Kondo lattice compounds with a minimum in resistivity around 8K and a coherence peak near 3K. AC magnetic susceptibility down to 100mK reveals an anti-ferromagnetic transition below 1.35 K.
