Magnetische Eigenschaften der Verbindungen BaMF4und Pb2MF6(M=Mn, Fe, Co, Ni, Cu, Zn)

摘要

Two series of double fluorides, BaMF4and Pb2MF6(M=Mn, Fe, Co, Ni, Cu, Zn) have been studied, the compounds of Cu and Zn differing in behaviour from the others. The Zn componds are diamagnetic, the Cu compounds paramagnetic. Pb2CuF6conforms toCurie'slaw while BaCuF4exhibits aCurie-Weissdeviation below 212° K
