Abstract

Ultrasonic velocity measurements in the two-dimensional antiferromagnet K₂NiF₄ as a function of temperature at several hydrostatic pressures show T_N to be very weakly pressure dependent. This result differs from previous estimates of the volume dependence of superexchange in similar compounds.
