通过改变组成元素，在填充方钴矿体系中发现了各种各样的强关联电子现象。独特的晶体结构导致新的功能，即使在系统中含有稀土元素与多个4 f -电子。在实验和理论研究的激烈竞争与合作下，对导致该系统多样性的几个基本原因的梳理取得了显著进展，如强c-f杂化、小CEF能级分裂、轨道自由度（多极）和氮族笼内位置自由度。然而，仍然有许多有吸引力的问题有待回答。
Full varieties of strongly correlated electron phenomena have been found in the filled skutterudite systems, by changing the constituent elements. The unique crystal structure leads to novel features even in the systems containing rare earth elements with plural number of 4 f -electrons. According to the intensive competitions and cooperation among experimental and theoretical research works, remarkable progress has been made in sorting out several basic origins that bring about the variety of this system, such as the strong c – f hybridization, the small CEF level splitting, the orbital degree of freedom (multipoles), and the positional degree of freedom within a pnictogen cage. However, there still remain many attractive questions to be answered.
