Iron-garnet magnetic field sensors with 100 pT/?Hz noise-equivalent field

January 1, 1990
Author(s)
M. N. Deeter, Allen Rose, Gordon W. Day
The sensitivity of Faraday-effect sensors incorporating diamagnetically substituted yttrium iron garnet (YIG) is potentially much higher than of sensors employing pure YIG. Results of Faraday rotation linearity and sensitivity measurements are presented

Laser Focusing of Atoms: A Particle Optics Approach

January 1, 1990
Author(s)
Jabez J. McClelland, M Scheinfein
The use of TEM* 01 ("donut") mode laser beam has been proposed as a means of focusing an atomic beam to nanometer scale spot diameters. We have analyzed the classical trajectories of atoms through a donut mode laser beam using methods developed for

Limitations on Electronic Mechanisms for High Temperature Superconducting Oxides

January 1, 1990
Author(s)
David R. Penn, Marvin Cohen, I Barbee
The effects of electronic mechanisms for electron pairing in high temperature superconducting oxides on both the transition temperature T c and the isotope effect parameter α are considered. It is shown that for the higher T c oxides, measured values of T

Material Dependence of Electron Inelastic Mean Free Paths at Low Energies

January 1, 1990
Author(s)
Shigeo Tanuma, Cedric J. Powell, David R. Penn
We have calculated electron inelastic mean free paths (IMFPs) for 50-2000 eV electrons in 31 materials (27 elements and 4 compounds). We present and discuss in this paper IMFP data for aluminum and gold in the 50-2000 ev Range. Substantial differences are
