Micromechanical Instruments for Ferromagnetic Measurements

January 1, 2003
Author(s)
John M. Moreland
I review some of the novel methods for measuring ferromagnetic properties of thin films based on micromechanical magnetometers. Measurements rely on the detection of mechanical forces or torques on samples deposited onto microcantilevers. Displacements of

Mode-Locked and Single-Frequency Er/Yb Co-Doped Waveguide Lasers

January 1, 2003
Author(s)
John B. Schlager, Berton Callicoatt, Richard Mirin, Norman Sanford
Erbium/ytterbium co-doped planar waveguide lasers are fabricated for low-jitter mode-locked operation and single-frequency operation at 1.54 υm. The passively mode-locked lasers produce picosecond pulses at fundamental repetition rates up to 1 GHz with

Molecular Dynamics Calculation of the Diffusivity of Sodium Chloride in Steam

January 1, 2003
Author(s)
Allan H. Harvey, Raymond D. Mountain
Molecular dynamics simulation is used to calculate the diffusivity of sodium chloride at infinite dilution in high-temperature steam at seven state points representing conditions of interest for the study of impurity deposition in steam turbines. Water is

Near-Field Plasmon Excitation on Structured Gold Films

January 1, 2003
Author(s)
B Dragnea, J Szarko, S Kowarik, J Feldmann, T Wiemann, S R. Leone
Surface plasmon polariton (SPP) localization control on rough metal surfaces has been achieved by varying the gap between a scanning near-field aperture probe and the surface. The qualitative explanation for this observation is based on the overlapping of
