Abstract
The isothermal section of the ytterbium-palladium-indium phase diagram was constructed at 600 °C in the Pd < 60 at% region, as a result of X-ray powder diffraction and scanning electron microscopy with energy dispersive X-ray analysis. The existence of a new ternary compound Yb5Pd2In was observed at this temperature, and its crystal structure was determined (structure type Mo5SiB2, space group I4/mcm, a =0.78820(2) nm, c = 1.41596(5) nm). Magnetic and thermodynamic properties of two ternary compositions YbPdIn4 and Yb17Pd50In33 were also investigated. Yb17Pd50In33 presents a stable trivalent Yb3+, whereas in YbPdIn4 the Yb ion is in a nearly divalent state.
