Field-Dependent Hall Coefficient in Potassium

P. A. Penz

Phys. Rev. Lett. 20, 725 (1968) - Published 1 April, 1968

Show Abstract

We report evidence that the Hall coefficient of K decreases with increasing field at very high magnetic fields. This is noteworthy because a metal with a simply connected, spherical Fermi surface should have a constant Hall coefficient. The observed behavior can be explained if the electronic ground state of K is a charge-density-wave state.

Divergences and Phonons in the Indirect Interaction

S. P. Bowen

Phys. Rev. Lett. 20, 726 (1968) - Published 1 April, 1968

Show Abstract

Divergences arising in the third-order perturbation-theory derivation of the indirect interaction between nuclear or ionic spins in a metal are avoided if the recoil of the localized spin is taken into account by including the phonon degrees of freedom. When this is done the form of the usual Ruderman-Kittel function is altered, particularly at small $R$ , where the singularity at the origin is removed.

Local Temperature-Gradient Contribution to Flux-Flow Viscosity in Superconductors

John R. Clem

Phys. Rev. Lett. 20, 735 (1968) - Published 1 April, 1968

Show Abstract

A normal-core model of type-II superconductors is used to calculate a contribution to the flux-flow viscosity arising from local temperature gradients in the core vicinity. The flux-flow resistivity versus temperature, according to this model, exhibits a minimum for impure, but not for pure, superconductors.

New Feature in Photoproduction of Pion Pairs

Phys. Rev. Lett. 20, 758 (1968) - Published 1 April, 1968

Show Abstract

Photoproduction of $π^{+} π^{-}$ pairs of invariant mass from 300 to 500 MeV at angles near 0° has been measured at photon energies from 1 to 2 GeV. The cross section is sharply peaked when the di-pion system is produced at 0°, and is coherent for complex nuclei. A simple extension of the Drell process gives good quantitative understanding of the data. We see no evidence for the hypothetical $σ$ meson.
