Predicting tunable nonreciprocal spin wave generation mediated by interfacial Dzyaloshinskii-Moriya interaction in magnonic heterostructures
Cameron A McEleney, Karen L Livesey, Robert E Camley +1
Thin, metallic magnetic films can support nonreciprocal spin waves due to the interfacial Dzyaloshinskii-Moriya interaction (iDMI). However, these films typically have high damping…
Curie-Weiss behavior and the "interaction" temperature of magnetic nanoparticle ensembles: local structure strongly affects the magnetic behavior
Robert E Camley, Rair Macêdo, Karen L Livesey
In this article, the Curie-Weiss type behavior and the appearance of an "interaction" or "ordering" temperature for a collection of magnetic nanoparticles is explored theoretically…
Breaking Space Inversion-Symmetry to Obtain Asymmetric Spin-Wave Excitation in Systems with Nonuniform Magnetic Exchange
Rair Macêdo, Arjun S. Kudinoor, Karen L. Livesey +1
We report on the consequences of non-uniform exchange in magnetic systems. The quantum mechanical exchange interaction between spins is responsible for the phenomenon of magnetic o…
Self-Consistent Local Mean-Field Theory for Phase Transitions and Magnetic Properties of FeRh
Brianne McGrath, Robert Camley, Karen Livesey
FeRh has a phase transition from an antiferromagnetic state (low temperature) to a ferromagnetic state (high temperature) at 360 K. Various explanations for this behavior have been…
Strain-mediated magnetoelectric coupling in magnetostrictive/piezoelectric heterostructures and resulting high frequency effects
K. L. Livesey
Magnetoelectric coupling terms are derived in piezoelectric/magnetostrictive (multiferroic) thin film heterostructures using Landau-Ginzburg free energy expansions in terms of stra…
The effect of transverse magnetic correlations on a coupled order parameter: shifted transition temperatures and thermal hysteresis
K. L. Livesey, R. L. Stamps
We use a Green's function method with Random Phase Approximation to show how magnetic correlations may affect electric polarization in multiferroic materials with magnetic-exchange…
