KAgF3 is a quasi-one-dimensional quantum antiferromagnet hosting a series of intriguing structural and magnetic transitions. Here we use powder neutron diffraction, ?SR spectroscopy, and density functional theory calculations to elucidate the low-temperature magnetic phases. Below TN1=29K we find that the material orders as an A-type antiferromagnet with an ordered moment of 0.52?B. Both neutrons and muons provide evidence for an intermediate phase at temperatures TN1

Abstract

Below TN1=29K we find that the material orders as an A-type antiferromagnet with an ordered moment of 0.52?B.
