    Notes: Fe/Mo multilayered thin films were grown on oxidized Si substrates by UHV e-beam evaporation. Both magnetic and structural results obtained from SQUID magnetometry, magnetoresistance (MR), small-angle x-ray scattering, large-angle x-ray scattering, and cross-sectional high-resolution electron microscopy are reported. Fe (30 A(ring))/Mo films with Mo thickness ranging from 7 to 25 A(ring) display oscillatory interlayer magnetic coupling. The maximum low-temperature negative MR is 2% for 11 A(ring) Mo layer thickness, while the minimum MR is 0.1% for 16 A(ring) Mo layer thickness. A series of Fe (30 A(ring))/Mo (11 A(ring)) films were grown at substrate temperatures (Ts) ranging from 150 to 475 K. Films grown at low Ts exhibit decreased coherence length and increased layer roughness, but only moderately reduced saturation field (Hs) and MR. Films grown at high Ts exhibit increased coherence length, increased interface thickness, and greatly reduced Hs and MR. Structural models for these films will be presented and correlated with magnetization and MR results.

    Real gas effects on hypersonic boundary-layer stability (1991)

    Notes: High-temperature effects alter the physical and transport properties of a gas, air in particular, due to vibrational excitation and gas dissociation, and thus the chemical reactions have to be considered in order to compute the flow field. Linear stability of high-temperature boundary layers is investigated under the assumption of chemical equilibrium and this gas model is labeled here as "real gas model.'' In this model, the system of stability equations remains of the same order as for the perfect gas and the effect of chemical reactions is introduced only through mean flow and gas property variations. Calculations are performed for Mach 10 and 15 boundary layers and the results indicate that real gas effects cause the first mode instability to stabilize while the second mode is made more unstable. It is also found that the second mode instability shifts to lower frequencies. There is a slight destabilizing influence of real gas on the Goertler instability as compared to the perfect gas results.
