✦ Synopsis
The conductivity, Seebeck effect and magnetic suscepUbfllty of the oxides La2-x A1 + x Cu2 O6-x/2 + 6 (A = Ca, Sr) have been mvestxgated These compounds which contain variable amounts of tnvalent copper are characterized by a hole conduction A progresswe evoluhon of the electron transport properties from a semi-conductor to a semi-metal is observed according to the amount of Cu 3+ These properties are interpreted m terms of a Mott band model The influence of the oxygen pressure during the electrical measurements ~s also considered
