Susceptibility and Dzyaloshinskii-Moriya interaction in the Haldane gap compound NENP

Abstract

The Haldane gap material NENP exhibits anomalies in its Knight shift, far infrared absorption and field-dependent gaps, which have been explained using the staggered $g$-tensor that occurs due to the low crystal symmetry. We point out that the low-temperature susceptibility is also anomalous and that a consistent interpretation of all data may require consideration of the Dzyaloshinskii-Moriya interaction.
