Abstract
Measurements of the magnetic moment of antiferromagnetic Cu at high fields reveal a new phase boundary originating from a previously undetected canting of the spins out of the Cu planes. This canting, together with the exponential temperature dependence of the two-dimensional correlation length, accounts quantitatively for the susceptibility peak at the Néel temperature. Enhancement of the conductivity in the ferromagnetic phase demonstrates a strong connection between the magnetism and charge transport.
