Anomalous Electrical Resistivity and the Existence of Giant Magnetic Moments in Ni-Cu Alloys

Abstract

The electrical resistivity of Ni-Cu alloys near the critical composition for ferromagnetism is found to remain anomalous up to temperatures of about 600\ifmmode^\circ\else\textdegree\fi{}K. This behavior is attributed to the existence of giant magnetic polarization clouds and to their ultimate disappearance at these temperatures.
