Structural Phase Transitions on Nickel at the Curie Temperature

March 16, 1981
Author(s)
J Hamilton, Terrence Jach
It is observed that a reversible step period rearrangement on clean nickel single-crystal surfaces occurs in the immediate vicinity of the Curie temperature. Reversible carbon segregation is observed on the same crystal surfaces below the Curie point. The

Resonant satellites in photoemission and Auger spectra of d-band metals

March 1, 1981
Author(s)
S Girvin, David R. Penn
Photoemission and Auger electron spectroscopy are powerful tools in the study of the electronic and magnetic properties of d band metals. In certain instances experimental spectra can be directly interpreted as a measure of some one body density of states

Spin Dependent Attenuation Lengths for Ferromagnets

March 1, 1981
Author(s)
R W. Rendell, David R. Penn
Spin dependent attenuation lengths (AL) as a function of the hot electron energy are calculated for Fe, Co, and Ni. If λ 1(λ 1) is the AL of an electron with spin parallel (antiparallel) to the majority spin direction of the ferromagnet then the quantity A

Temperature variation of SAW power flow angle

February 19, 1981
Author(s)
Dylan F. Williams, F Y. Cho
The power flow angle of surface acoustic waves in quartz not on a crystalline axis of symmetry is shown to vary rapidly with temperature. Experimental results and theoretical calculations are presented demonstrating the dependence of the acoustic power

Polarized Low Energy Electron Diffraction (PLEED) from W(100)

February 15, 1981
Author(s)
G Wang, Robert Celotta, Daniel T. Pierce
A set of polarized low-energy-electon diffraction (PLEED) data from a W(100) surface measured using a polairzed electron beam is presented. The data include conventional LEED profilesI(E,θ) as well as S(Eθ profiles which measure the spin dependence of the

Spin Dependent Absorption of Electrons in a Ferromagnetic Metal

February 9, 1981
Author(s)
H Siegmann, Daniel T. Pierce, Robert Celotta
It is found that the current collected by a ferromagnet placed in an electron beam depends on the orientation of the incident electron spin. At certain energies, only electrons with spins parallel or antiparallel to the net surface spin density cause a net
