Antiferromagnetic cavity magnon polaritons in collinear and canted phases of hematite
I. Boventer, H. T. Simensen, B. Brekke +5
Cavity spintronics explores light matter interactions at the interface between spintronic and quantum phenomena. Until now, studies have focused on the hybridization between ferrom…
Strong bulk spin-orbit torques quantified in the van der Waals ferromagnet Fe3GeTe2
Franziska Martin, Kyujoon Lee, Maurice Schmitt +13
The recent emergence of magnetic van der Waals materials allows for the investigation of current induced magnetization manipulation in two dimensional materials. Uniquely, Fe3GeTe2…
Magnon spin current induced by triplet Cooper pair supercurrents
Lina G. Johnsen, Haakon T. Simensen, Arne Brataas +1
At the interface between a ferromagnetic insulator and a superconductor there is a coupling between the spins of the two materials. We show that when a supercurrent carried by trip…
Room temperature antiferromagnetic resonance and inverse spin-Hall voltage in canted antiferromagnets
I. Boventer, H. T. Simensen, A. Anane +3
We study theoretically and experimentally the spin pumping signals induced by the resonance of canted antiferromagnets with Dzyaloshinskii-Moriya interaction and demonstrate that t…
Spin pumping between noncollinear ferromagnetic insulators through thin superconductors
Haakon T. Simensen, Lina G. Johnsen, Jacob Linder +1
Dynamical magnets can pump spin currents into superconductors. To understand such a phenomenon, we develop a method utilizing the generalized Usadel equation to describe time-depen…
Observation of magnon-polarons in a uniaxial antiferromagnetic insulator
Junxue Li, Haakon T. Simensen, Derek Reitz +6
Magnon-polarons, a type of hybridized excitations between magnons and phonons, were first reported in yttrium iron garnet as anomalies in the spin Seebeck effect responses. Here we…
Macroscale non-local transfer of superconducting signatures to a ferromagnet in a cavity
Andreas T. G. Janssønn, Haakon T. Simensen, Akashdeep Kamra +2
Cavity spintronics recently heralded non-local magnonic signal transfer between magnetic samples. Here we show that by including superconductors in the cavity, we can make use of t…
Magnon decay theory of Gilbert damping in metallic antiferromagnets
Haakon T. Simensen, Akashdeep Kamra, Roberto E. Troncoso +1
Gilbert damping is a key property governing magnetization dynamics in ordered magnets. We present a theoretical study of intrinsic Gilbert damping induced by magnon decay in antife…
Magnon-polarons in cubic collinear Antiferromagnets
Haakon T. Simensen, Roberto E. Troncoso, Akashdeep Kamra +1
We present a theoretical study of excitations formed by hybridization between magnons and phonons - magnon-polarons - in antiferromagnets. We first outline a general approach to de…
Magnetostriction in Antiferromagnets
Haakon T. Simensen, Roberto E. Troncoso, Arne Brataas
We consider magnetostriction in magnetic materials. Starting from a microscopic lattice model of the magneto-elastic coupling, we derive the continuum magnetostriction Hamiltonian…
Tunable superconducting critical temperature in ballistic hybrid structures with strong spin-orbit coupling
Haakon T. Simensen, Jacob Linder
We present a theoretical description and numerical simulations of the superconducting transition in hybrid structures including strong spin-orbit interactions. The spin-orbit coupl…
