“…The decrease of T c by magnetic field is in an ordinary way. It seems that T c and T 0 cross at B = 100 G. A very similar phase diagram is also established in β-pyrochlore oxide KOs 2 O 6 which is conjectured as a good candidate of rattling induced superconductor [5,6]. A phase transition, which is related to the rattling, aside of the superconductivity is observed in KOs 2 O 6 .…”

LaOs 4 P 12 is known as a superconductor with a T c of 2.0 K. The low-temperature specific-heat and the electrical resistivity measurements under magnetic fields using high quality samples revealed that LaOs 4 P 12 is not a simple superconductor. Another phase transition with a transition temperature which is very close to T c exists. The electrical resistivity shows an increase below 3.5 K. The newly found transition disappears by small amount of Ce-impurity.

“…Multinary osmium oxides have been found to feature remarkable electronic and magnetic properties such as superconductivity in AOs 2 O 7 (A ¼ Cs, Rb, and K) [1], metal-insulator transitions in NaOsO 3 and Cd 2 Os 2 O 7 [2,3], and high T C ferrimagnetic insulators Sr 2 CrOsO 6 [4]. The pentavalent osmium (5d 3 ) appears to produce high magnetic transition temperature.…”

“…Caged type structures have received considerable attention due to their fascinating properties [19]. Three cage-type compounds have been comprehensively studied over the past decade as "rattling-good" materials: Ge/Si clathrates, filled skutterudites (RT 4 X 12 ), and β-pyrochlore oxides (AOs 2 O 6 ) [19].…”
