Effects of O 2 , N 2 , H 2 , and H 2 O on characteristics of vapor‐deposited Ni‐Fe films are determined with the aid of quadrupole and monopole gas analyzers. Data obtained for films deposited in getter‐ion or oil‐diffusion‐type vacuum systems show that the presence of high oxygen...
The transitions between phases and different states of crystallographic order in films are systematically examined. The experimental data of various workers are comprehensively connected and interpreted. By combining this evidence with theoretical considerations, the many analogies between two‐...
A laser system using bleachable‐filter Q‐switching has enabled us to obtain simultaneous ``giant pulses'' from five ruby laser oscillators. The beams from the different oscillators were found to be phase‐locked; the beam divergence was limited by the initial ruby quality. Two other systems...
The linearized field equations for ion acoustic and electromagnetic waves in a low‐pressure gas discharge or semiconductor are considered. Boundary conditions at a density discontinuity and a plasma‐air surface are examined and expressions are derived for the reflected and transmitted fields...
The diffusion of gold into copper grain boundaries from thin sources has been studied from 760° to 625°C. The activation energy for the grain‐boundary diffusion of gold into copper is 25 kcal∕mole. At the lower temperature, there was observed surface depletion of gold at the grain boundary...
The method of determining charge‐carrier mobility by combining conductance with thermogravimetric measurements is discussed. The conditions of validity of the method are analyzed for one example. It is shown that the analysis of such measurements may permit estimation of an upper limit for the...
The effect of temperature and strain rate on the flow stress of β‐AgMg single crystals was investigated in the temperature range of 77° to 900°K and strain‐rate range of 10 −4 to 10 4 sec −1 . The low‐temperature data were found to obey the predictions of the Peierls mechanism up to...
