Abstract

Monocrystalline nickel-cobalt-manganese-copper oxide having a cubic spinel structure over a broad range of concentration ratios of manganese/cobalt/nickel/copper, including methods of producing such monocrystals, particularly those having a quaternary cubic spinel structure. Sensors having desirable electrical properties are disclosed, which sensors comprise at least a portion of such monocrystals. In particular, such sensors are highly accurate temperature sensors or thermistors having high sensitivity, good reproducibility and improved aging characteristics.
