This is the summary of a paper which discussed neutron diffraction techniques as applied to helical type and related spin structures, and illustrated these techniques with results from recent investigations on MnAu2 and metallic holmium.
Abstract A method of measuring the pH‐dependent cation‐exchange capacity of soils is described and data for 15 surface soils are presented and discussed. The pH‐dependent cation‐exchange capacity was found to be equivalent to the exchange acidity not displaced by a neutral KCl solution but displaced by buffered BaCl 2…
An exact formula for the intensity reflectance of light incident normally on a nonabsorbing nonhomogeneous thin film is derived for the case where the refractive index changes exponentially with film thickness and the film is bounded on either side by nonabsorbing homogeneous semi-infinite media. A formula for the pha…
Abstract Chrom(III)‐oxydchlorid CrOCl wird durch Umsetzung von Oxyden mit CrCl 3 , in gut kristallisierter Form erhalten. Die chemisch recht beständige Verbindung zerfällt beim Erhitzen an der Pumpe in Cr 2 O 3 und CrCl 3 g. In Gegenwart eines hinreichenden CrCl 3 ‐ Drucks ist CrOCl dagegen beständig und im Temperatur…
The kinetics of hydrogen attack of a killed steel have been studied in the temperature range 800 to 1200 F and in the pressure range 450 to 950 psi hydrogen. A quantitative relationship between incubation of attack and temperature and pressure has been obtained. Based on these results and those from a series of iron a…

A number of single-crystal films of iron, nickel, and Permalloy were made epitaxially by evaporation onto(001) cleavage surfaces of NcCl and MgO. Magnetic anisotropies for the rotation of magnetization within the plane as well as out of the plane of the film were measured. Values of the observed fourth-order anisotrop…
A calculation of the field due to the ring current in the porphyrin system is given and shown to account for the observed chemical shifts of the protons in porphyrins. Also variations of the ring current are shown to account for the observed variations in the proton chemical shifts of different porphyrin molecules.
The temperature of a thin metal foil illuminated by the high intensity electron beam of the modern microscope may at the centre of illumination reach a temperature above that of the melting point of iron. An attempt has been made to measure and calculate the temperature distribution for any given metal under various i…
Abstract Es wird ein kurzer Überblick über den derzeitigen Stand der Braunsteinforschung gegeben. Die Untersuchungsmethoden werden mitgeteilt. δ‐Braunsteine werden nach mehreren Verfahren hergestellt und charakterisiert. Beim Erhitzen an der Luft wandeln sich die δ‐Braunsteine bei etwa 100 °C in γ″‐MnO 2 um. Bei weite…
The ordering transformation in the alloy Ni3Mn has been investigated using both magnetic and neutron diffraction techniques. These measurements were made with alloys that were allowed to relax to nearly equilibrium states of order over a range of temperatures above and below the critical ordering temperature. In addit…

An analytic function is proposed in a parametric form which displays the character of an adjustable hysteresis loop. The type of function used was suggested by the phase-frequency characteristic of a conventional phase shift network. There are two parameters in the analytic function, one of which controls the width of…

Magnetic and crystallographic properties have been studied of the system (La 1- y Sr y )MnO x with varying values of y and x . It is found that the compounds with y =1 crystallize in the perovskite-like structures provides that x is lower than a certain limit. Perovskite-like SrMnO x , containing both Mn 3+ and Mn 4+…
