Remanent-magnetization reversal in nickel-manganese alloys

October 1, 1978
Author(s)
Ronald B. Goldfarb, T. Satoh, Carl E. Patton
Weakly ordered nickel-manganese alloys, field cooled to 4 K, exhibit a reversal in remanent magnetization upon warming. The reversal is dependent on the state of atomic order the cooling field. A local environment model and Mn-rich aggregates, which are

Smoke Measurements in Large and Small Scale Fire Testing. Final Report.

October 1, 1978
Author(s)
Richard W. Bukowski
The extinction beam photometer is the most widely used instrument for taking smoke measurements in fire testing. Most existing designs were found to be inaccurate and unreliable for measurements where smoke detection performance is evaluated due to the low

UV Photoemission for Rare Gases Implanted in Ge

August 21, 1978
Author(s)
B Waclawski, John William Gadzuk, J F. Herbst
The first ultraviolet photoemission spectra of the valence electrons of rare-gas atoms, implanted by ion bombardment into an amorphous Ge matrix, are presented here. The positions of the peaks in the observed spectra are shifted relative to gas-phase
