Non-Collinear Magnetic Phases of a Triangular-Lattice Antiferromagnet and Doped CuFeO
Randy S. Fishman, Satoshi Okamoto
We obtain the non-collinear ground states of a triangular-lattice antiferromagnet with exchange interactions up to third nearest neighbors as a function of the single-ion anisotrop…
Giant Antiferromagnetically Coupled Moments in a Molecule-Based Magnet with Interpenetrating Lattices
Randy S. Fishman, Satoshi Okamoto, William W. Shum +1
The molecule-based magnet [Ru(OCMe)][Cr(CN)] contains two weakly-coupled, interpenetrating sublattices in a body-centered cubic structure. Although the field-de…
Spin Rotation Technique for Non-Collinear Magnetic Systems: Application to the Generalized Villain Model
J. T. Haraldsen, R. S. Fishman
This work develops a new generalized technique for determining the static and dynamic properties of any non-collinear magnetic system. By rotating the spin operators into the local…
Spin-Wave Instabilities and Non-Collinear Magnetic Phases of a Geometrically-Frustrated Triangular-Lattice Antiferromagnet
J. T. Haraldsen, M. Swanson, G. Alvarez +1
This paper examines the relation between the spin-wave instabilities of collinear magnetic phases and the resulting non-collinear phases for a geometrically-frustrated triangular-l…
