Electronic properties of a new ternary f-electron system RP ₃Al<SUB>5</SUB> (R: rare earth elements) have been investigated. RPt ₃Al<SUB>5</SUB> crystalizes in the CePt ₃Al<SUB>5</SUB>-type orthorhombic structure where R atoms form 1-dimensional chains along the b-axis. LaPt ₃Al<SUB>5</SUB> shows superconductivity below 0.4 K, while others show magnetic ordering. CePt ₃Al<SUB>5</SUB> orders antiferromagnetically below T<SUB>N</SUB> = 1.2 K with spontaneous moment and shows successive magnetic transition at T<SUB>m</SUB> = 0.9 K. The nearly divalent antiferromagnet EuPt ₃Al<SUB>5</SUB> indicates an unusual valence cross-over behavior into the nearly trivalent state under high pressure of 9 GPa. It is also found that most of RPt ₃Al<SUB>5</SUB> orders antiferromagnetically and, in some cases, shows characteristic features in magnetic suscep- tibility, where the broad maximum appears slightly above T<SUB>N</SUB>, reecting the low-dimensional nature.
