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…
Oriented Asymmetric Wave Propagation and Refraction Bending in Hyperbolic Media
Rair Macêdo, Thomas Dumelow, Robert E. Camley +1
Crystal quartz is a well-known anisotropic medium with optically active phonons in the THz region where hyperbolic phonon-polaritons can be excited. Here, we use this material to i…
Spin wave power flow and caustics in ultrathin ferromagnets with the Dzyaloshinskii-Moriya interaction
Joo-Von Kim, Robert L. Stamps, Robert E. Camley
The Dzyaloshinskii-Moriya interaction in ultrathin ferromagnets can result in nonreciprocal propagation of spin waves. We examine theoretically how spin wave power flow is influenc…
Small dimensional microstrips embedded with ferromagnetic layers: Numerical simulations and experimental results
Jonah N. Gollub, Bijoy Kuanr, Zibigniew Celinski +2
We use a numerical electromagnetic simulation software to investigate a filtering device consisting of a small dimensional microstrips embedded with a thin layer of ferromagnetic m…
