We have prepared superconducting thin films of iridium from which we have fabricated Dayem-type microbridges and Al-Al2O3-Ir tunnel junctions that have I-V characteristics typical of these types of Josephson devices. Using the Al-Al2O3-Ir tunnel junc

Oxidation of some simple organometallic compounds with tetracyanoquinodimethan (TCNQ) in acetonitrile gave metal derivatives of TCNQ 2− which were characterized by infrared and X-ray photoelectron spectroscopy and magnetic susceptibility. Strong, l

A potentiometric technique for accurately determining a fixed voltage ratio has been developed which employs a voltbox subdivided for optimum self‐calibration. The calibration procedure minimizes the effects of resistor self‐heating and interconn

Various ripple effects in uniaxial polycrystalline magnetic films have been related by several authors to an effective single‐grain crystalline anisotropy constant K. If either an isotropic planar stress σ or a uniaxial strain e33 is applied to su

High accuracy determinations of 2 e/h using the ac Josephson effect require correspondingly accurate measurements of small dc voltages. In the preliminary stages of a determination of 2 e/h with substantially improved accuracy, two different potentio

This paper describes in detail the procedures, methods and measurements used to establish a new definition of the U.S. legal volt via the ac Josephson effect. This new definition has been made possible by the use of thin film tunnel junctions (capabl
