Superconductivity in the platinum germanides MPt4Ge12 (M = rare-earth or alkaline-earth metal) with filled skutterudite structure.
New germanium-platinum compounds with the filled-skutterudite crystal structure were synthesized. The crystal structure and composition were investigated by x-ray diffraction and microprobe analysis. Magnetic susceptibility, specific heat, and electrical resistivity measurements evidence superconductivity in LaPt4Ge12 and PrPt4Ge12 below 8.3 K. The parameters of the normal and superconducting s...
متن کاملResonant oscillation of misch-metal atoms in filled skutterudites.
We investigate vibrational behaviors in misch-metal filled antimony skutterudites in the time domain. At higher filling ratios of guest atoms, the vibration frequency approaches that of the cage structure and the amplitude becomes stronger. Furthermore, the reduction of lattice thermal conductivity over a wide temperature range can be explained using the measured resonant vibrational frequency....

A number of new binuclear complexes have been synthesised by interaction of stable Ni(II) and Cu(II) metal chelates of p-Methylisonitroacetosophenone with Alkaline earth metal salts having general formula[Ma(p-MeINAP)2MbL2 or MbX2]where Ma=Ni(II) or Cu(II),p-MeINAP = deprotonated pMethyiIsonitrosoacetophenone, Mb= Ca ++ or Mg ++ ,L = deprotonated ortho amino benzoic acid and 8hydroxyquinoline X...
متن کاملAlkaline-earth-metal atoms as few-qubit quantum registers.
We propose and analyze a novel approach to quantum information processing, in which multiple qubits can be encoded and manipulated using electronic and nuclear degrees of freedom associated with individual alkaline-earth-metal atoms trapped in an optical lattice. Specifically, we describe how the qubits within each register can be individually manipulated and measured with subwavelength optical...
متن کاملInfrared study on the metal – insulator transition in filled skutterudites RRu 4 P 12 ð R 1⁄4 Pr ; Sm Þ
Infrared study has been made on the filled skutterudites PrRu4P12 and SmRu4P12; which undergo a metal–insulator (M–I) transition at TMI 1⁄4 60 and 16 K; respectively. The opening of a charge gap for the two compounds are clearly observed below TMI: For PrRu4P12; new phonon peaks are also observed below TMI; which suggests that the crystal symmetry is lowered. On the other hand, no additional pe...
