Ordered Magnetic State in PrFe$_{4}$Sb$_{12}$ Single Crystals

ORAL

Abstract

Single crystals of the filled skutterudite compound PrFe$_{4}$Sb$_{12}$ were prepared and characterized via X-ray and neutron diffraction, specific heat, electrical resistivity, and magnetization measurements. Long range magnetic ordering occurs at $T_{\mathrm{c}} \approx 4.1$~K. The magnetic structure consists of ordered moments on both Pr and Fe sites and may be ferrimagnetic. The electrical resistivity exhibits a very weak dependence on both applied magnetic field and pressure. Specific heat measurements indicate an enhanced effective mass.
