Abstract
We have examined the ground-state properties of the putative intermediate valency and/or charge density wave (CDW) system via resistivity, specific heat, magnetic susceptibility, and x-ray absorption spectroscopy. The bulk properties confirm a CDW-type anomaly at , but show that all the Yb ions are in an integral trivalent state. Additionally, our low-temperature measurements reveal two magnetic transitions at 2.3 and , respectively. The compound shows Kondo-lattice-type behavior that might be responsible for the weak-coupling nature of the CDW evidenced by the specific heat data.
