Antibonding and Electronic Instabilities in GdRu2X2 (X = Si, Ge, Sn): A New Pathway Toward Developing Centrosymmetric Skyrmion Materials
Dasuni N. Rathnaweera, Xudong Huai, K. Ramesh Kumar +4
Chemical bonding is key to unlocking the potential of magnetic materials for future information technology. Magnetic skyrmions are topologically protected nano-sized spin textures…
Calculating Bardeen-Cooper-Schrieffer and Magnetic Superstructure Electronic States with
Evgeny Plekhanov, Andrei Tchougréeff, Richard Dronskowski
We propose the (Theta-Phi) package which addresses two of the most important extensions of the essentially single-particle mean-field paradigm of the computational solid state…
Magnetic inhomogeneity in the copper pseudochalcogenide CuNCN
A. Zorko, P. Jeglič, M. Pregelj +4
Copper carbodiimide, CuNCN, is a geometrically frustrated nitrogen-based analogue of cupric oxide, whose magnetism remains ambiguous. Here, we employ a combination of local-probe t…
c-a-ca Mean Field RVB Model of CuNCN Physics. Structure Manifestations of the RVB Transitions
A. L. Tchougréeff, R. Dronskowski
We propose a new form of the frustrated Heisenberg antiferromagnetic Hamiltonian with spatially anisotropic exchange parameters Jc, Ja, and Jac extended along the c, a, and a +/- c…
Tentative Structural Features of a Gapped RVB State in the Anisotropic Triangular Lattice
A. L. Tchougréeff, R. Dronskowski
The self-consistency equations for the independent order parameters as well as the free energy expression for the mean-field RVB model of the spin-1/2 Heisenberg Hamiltonian on the…
Unconventional Magnetism in a Nitrogen-Based Analogue of Cupric Oxide
A. Zorko, P. Jeglič, A. Potočnik +6
We have investigated the magnetic properties of CuNCN, the first nitrogen-based analogue of cupric oxide, CuO. Our muon spin relaxation, nuclear magnetic resonance and electron spi…
