Magnetic order of Dy and Fe moments in antiferromagnetic DyFeO probed by spin Hall magnetoresistance and spin Seebeck effect
G. R. Hoogeboom, T. Kuschel, G. E. W. Bauer +3
We report on spin Hall magnetoresistance (SMR) and spin Seebeck effect (SSE) in single crystal of the rare-earth antiferromagnet DyFeO with a thin Pt film contact. The angula…
Cryogenic spin Seebeck effect
Mehrdad Elyasi, Gerrit E. W. Bauer
We present a theory of the non-linearities of the spin Seebeck effect (SSE) in a ferromagnetic nanowire at cryogenic temperatures. We adopt a microscopic quantum noise model based…
Spin-Wave Doppler Shift by Magnon Drag in Magnetic Insulators
Tao Yu, Chen Wang, Michael A. Sentef +1
The Doppler shift of the quasiparticle dispersion by charge currents is responsible for the critical supercurrents in superconductors and instabilities of the magnetic ground state…
Theory of Transport in Ferroelectric Capacitors
Gerrit E. W. Bauer, Ryo Iguchi, amd Ken-ichi Uchida
We present a time-dependent diffusion theory for heat and polarization transport in a planar ferroelectric capacitor with parameters derived from a one-dimensional phonon model. We…
Circulating cavity magnon polaritons
Weichao Yu, Tao Yu, Gerrit E. W. Bauer
We predict magnon polariton states circulating unidirectionally in a microwave cavity when loaded by a number of magnets on special lines. Realistic finite-element numerical simula…
Equilibrium current vortices in rare-earth-doped simple metals
Adam B. Cahaya, Alejandro O. Leon, Mojtaba Rahimi Aliabad +1
Dilute alloys of rare earths have played a vital role in understanding magnetic phenomena. Here, we model the ground state of dilute 4f rare-earth impurities in light metals. When…
