Magnetic and transport properties of ternary indides of type R2CoIn8 (R=Ce, Pr, and Dy)

Abstract

We have synthesized and investigated the magnetic and transport properties of a series of compounds, R 2 CoIn 8 (R = rare earth). Compounds form in single phase with a tetragonal structure (space group P4/mmm, no. 162). The Ce compound shows heavy fermion behavior. The magnetic susceptibility of Pr 2 CoIn 8 shows a marked deviation from the Curie-Weiss behavior at low temperatures, which is attributed to the crystalline electric field effects. Heat capacity and magnetization measurements show that Dy 2 CoIn 8 undergoes a magnetic transition at 17 K and a second transition near 5 K, the latter of which may be due to spin reorientation. Magnetization of this compound shows two metamagnetic transitions approximately at 3.6 T and 8.3 T.

“…Apart from this, a high-pressure transport study is reported in the case of Ce 2 CoIn 8 [9]. We have reported on R 2 CoIn 8 (R = Ce, Pr and Dy) compounds [10]; Dy 2 CoIn 8 shows interesting magnetic properties and Pr 2 CoIn 8 shows crystal field effects.…”
