The properties of small particles can be markedly different from the bulk. A classical thermodynamic treatment of the melting and freezing of small particles, including the effects of surface-induced order, predicts an energy barrier between a surfac

Using third sound, we have found that helium atoms can form a superfluid in direct contact with the crystalline surface of solid hydrogen. An anomalous phase marked by a second line of transitions similar to the Kosterlitz-Thouless transition has als

Because of possible effects from (110) twin planes and {ital a}-{ital b} anisotropy in YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}}, measurements on untwinned crystals are desirable. We have measured the Hall effect and resistivity simultaneously in unt

Using third sound resonance below 1 K, for4He on solid H2 and D2 surfaces, we have found new phenomena. On H2 we find surface superfluidity for4He coverages less than one layer, with the zero temperature Kosterlitz-Thouless (KT) transition extrapolat

We present a measurement of the Hall coefficient {ital R}{sub {ital H}} for an untwinned single crystal of YBa{sub 2}Cu{sub 3}O{sub 7{minus}{ital x}}. The crystal was produced by a method that does not involve thermomechanical detwinning, and has a r

Using vortex pair motion, we have measured the vortex diffusivity below the Kosterlitz-Thouless transition temperature (T KT) in atomically thin superfluid helium films on both argon and neon substrates. The diffusivities are on the order ofħ/m near

Precision measurements of third sound in atomically thin4He films on Ne, Ar, and CO2 substrates reveal a periodic structure not corresponding to whole layers. Treating the He film as an incompressible, continuous fluid, the data indicate that the che

Small metal particles in the range of a few nanometers in diameter are seen to progressively disorder when the 100 keV electron beam of a Scanning Transmission Electron Microscope (STEM) is held stationary on the particle. The diffraction pattern of

Thermodynamic fluctuations cause small regions of a sample to enter the superconducting state as the temperature approaches Tc from above. Conversely, small regions fluctuate into the normal state below Tc. We review the value of measuring fluctuatio
