✦ Synopsis

A technique has been developed for measuring the Hall coefficient which is based on the invariance of the antisymmetric part of the resistivity tensor with respect to rotational transformation. This technique permits the Hall coefficient for any orientation to be determined on one single crystal. I n this paper it has been applied t o copper. The results thus obtained are used for the calculation of the Hall conductivity which, in turn, yields information on characteristic properties of the lermi surface.Ausgehend Ton der Invarianz des antisymmetrischen Anteils des Widerstandstensors gegenuber Drehtransformationen urn seine eigene Achse wurde ein MeBverfahren entwickelt, das es ermoglicht, den Hallkoeffizienten fur alle Winkelorientierungen im Raum an einem einzigen Einkristall zu bestimmen. Dieses Verfahren wurde fiir Kupfer angewendet. Die Ergebnisse gestatten eine Berechnung der Hall-Leitfahigkeit, welche ihrerseits Aussagen iiber charakteristische Gror613en der Fermiflache zuliilt.
