The optical electrical and magnetic properties of the europium chalcogenides and the rare earth pnictides
TL;DR: Ferromagnetic material is defined by the spontaneous parallel alignment of atomic magnetic moments over relatively large regions of a solid as discussed by the authors, which can be of the ferro-, ferri-, antiferro-, or metamagnetic kind.

N.G. Eror,J.B. Wagner +1 more
TL;DR: In this article, electrical conductivity and thermogravimetric measurements on single crystalline cobaltous oxide indicate that the electronic and atomic defect concentration is a function of the 1 4 power of the oxygen partial pressure over the temperature range of 900°-1200°C and 10°−10 −4 atm.
