New filled skutterudite phosphides with heavy lanthanide (including Y), LnT4P12 (Ln = heavy lanthanide and Y; T = Fe, Ru and Os) have systematically been prepared at high temperatures and high pressures. The new relationship between lattice constants and atomic numbers of lanthanides was obtained for filled skutterudite phosphides. Electrical and magnetic properties of the skutterudites with heavy lanthanide have been studied at low temperatures. The superconductivity, the paramagnetic behavior, ferromagnetic and antiferromagnetic transitions were found for the new filled skutterudites prepared at high pressure. Thus, these compounds are classified to four groups by their magnetic properties. The physical properties of new filled skutterudite phosphides with heavy lanthanide (including Y) are discussed.
