Magnetic Equations of State of Heisenberg Ferromagnets, EuS and Its Sr-Diluted Derivatives, in a High Field Region

1,2 - Diphenyl - 3,3 - dimethyl - diphosphirane (1,2- Diphenyl- 3,3- dimethyl-diphosphacyclopropane) (1) is formed by the reaction of K(C6H5)P–P(C6H5)K with 2,2-dichloropropane in n-pentane at —30 °C. It could be detected and identified by its 31P NMR singlet at —122 ppm, which lies in the high field region characteristic for phosphorus three-membered ring compounds, as well as by its mass spectrum. Besides, (PC6H5)5 and several cyclocarbaphosphanes of ring sizes five and six are formed. After the reaction of (CH3)3Si(C6H5)P–P(C6H5)Si(CH3)3 with methylene iodide a weak 31P NMR signal at —147 ppm could be observed, which probably corresponds to the 1,2-diphenyl-diphosphirane.

High Field Region

Bowers, Legendy & Rose (1961) have recently found that when a strong magnetic field is applied to a pure metal sample at 4.2 °K, the mutual inductance between two coils surrounding the sample shows a resonant peak at a frequency (typically of order 100 c/s) which varies with the applied field strength. We show that this effect makes possible accurate measurements of the Hall coefficient in the high-field region, where the transverse electric field due to the Hall effect exceeds the longitudinal resistive field. The theory of the effect has been developed for a sample in the form of a thin rectangular plate, and verified in some detail experimentally. The effect has been used to measure the Hall coefficients of Li, Na, K, A1 and In at 4.2 °K. Except for Li, where our data do not extend to the high-field region, we find that the high-field Hall coefficients of all these metals are about 5 % larger in magnitude than the theoretical high-field values. We have also observed the effect in InSb at room temperature, where it occurs at a frequency of order 100 Mc/s and may have practical applications.
