Abstract:

This bibliography lists publications related to the double fluorides XMnF3, where X is K, Rb or Cs. These materials are antiferromagnetic with Neel temperatures of 88.3 deg. K, 82.6 deg. K and 53.5 deg. K, respectively. Considerable interest has been shown in their properties since about 1960. They are characterized by having large exchange Hex about 10 to the 6th power Oe and small crystalline anisotropy H 10 Oe. Antiferromagnetic resonance AFMR can be observed, therefore, at microwave frequencies without the need for very large magnetizing fields. Further, there is a strong hyperfine interaction that causes pronounced coupling between the nuclear magnetic resonance NMR of the Mn55 nuclei and the AFMR modes. Hence much of the published work to date has dealt with magnetic resonance.
