Abstract
Nickel ferrite, as ordinarily prepared, has a dc resistivity of 104 to 106 ohm‐centimeters. It has been found that by incorporating small amounts of manganese or cobalt, the resistivities can be increased to 1010 or 1011 ohm‐centimeters. Presumably, replacing Fe++ or Ni+++ with Mn or Co ions eliminates the easy conduction paths otherwise provided by the former ions. Further work is required to elucidate the exact mechanism.Keywords
