Abstract

Using neutron diffraction a random-field generated memory is observed in K2NixZn1−xF4 with x = 0.96, 0.85, and 0.75. The intensities and profiles of magnetic Bragg reflections are found to follow unique trajectories determined by switching the external magnetic field on and off while cooling. The effect, associated with a inhomogeneous spread in TN on a microscopic scale, is a direct manifestation of freezing in of multi-domain states at the ordering temperature.
