以单晶形式制备了填态的方角铁矿化合物Pr 0.87Fe4Sb12，并通过x射线衍射、中子衍射、比热、电阻率和磁化测量对其进行了表征。长程磁有序发生在Tc<4.1 K，体磁化强度的临界指数sb=0.57,g=0.884, d=2.55。磁性结构由Pr和Fe位置上的有序矩组成，可能涉及铁磁排列。在大多数温度下，电阻率对外加磁场和压力的依赖关系都很弱，但在低温下，电阻率的幂律温度依赖关系随磁场而变化。比热测量表明有效质量增强。
The filled skutterudite compound Pr 0.87Fe4Sb12 was prepared in single-crystal form and characterized via x-ray-diffraction, neutron-diffraction, specific-heat, electrical-resistivity, and magnetization measurements. Long-range magnetic ordering occurs at Tc<4.1 K, with the bulk magnetization described by the critical exponentsb=0.57,g=0.884, andd=2.55. The magnetic structure consists of ordered moments on both Pr and Fe sites and may involve a ferrimagnetic arrangement. The electrical resistivity exhibits a very weak dependence on both applied magnetic field and pressure at most temperatures, but at low temperatures, its power-law temperature-dependence varies with magnetic field. Specific-heat measurements indicate an enhanced effective mass.
