The conductivity of nickel ferrous ferrite shows a transition as a function of applied pressure around 30 kbar. A Mott “ T - 1 4 ” law is obeyed on both sides of the transition so that an explanation in terms of a metal-insulator transition canno

Polycrystalline samples of Fe3O4-xFx with 0 < x < 0.25 have been prepared by pressure-sintering. Measurements are reported of the resistivities and Seebeck coefficients as a function of temperature. Simple narrow band or small-polaron models do not a

A double diode subharmonically pumped mixer is described. A diode-whisker contacting arrangement has been developed which avoids many of the problems associated with whisker contacts. Early tests indicate that the circuit structure is rugged and capa

The magnitude and temperature of the Verwey transition have been investigated for germanium‐ and fluorine‐doped magnetite to assess the effectiveness of A sublattice and anion substitutions in displacing and suppressing the transition. It is foun

An automated vibrating sample magnetometer (VSM) has been constructed in order to facilitate measurements of the magnetization of conducting samples of different fields and temperatures over a period of time. The principal features of the VSM are lar
