Reports on the discovery by K. Tangaki and colleagues at electronic company NEC that buckyballs doped with cesium and rubidium atoms conduct electricity without resistance at temperatures up to 33 Kelvin. Claimed highest temperature for superconductivity in a non-ceramic material; Claim of the NEC group that superconductivity reported at 29.5 Kelvin in cesium-doped buckyballs by another group could not be done.

    In the pressure range 14–35 GPa we have measured the resistance of shock-compressed nickel. Its abrupt decrease at ∼23 GPa is noted, and the boundaries of the existence of this anomaly (±1 GPa) are determined. It is shown that the observed anomaly can be linked with a structural...

    Electrical resistivity and heat conductivity of the LuInCu[sub 4] semimetal have been studied in the 4.2–300-K range. For T >= 100 K, the bipolar heat-conductivity component (κ[sub bip]) was found to contribute. Data on κ[sub bip] have been used to estimate the electron and hole...
