description

Abstract The phase diagram for nuclear magnetic order is elemental copper and the corresponding ordering vectors were investigated by neutron diffraction at nanokelvin temperatures. The intermediate phase is characterized by an ordering vector (O 2 3 2/3 . This is the first time that this type of order is observed in an fcc antiferromagnet.
