Magnon hall effect
WebThermal Magnon Hall Effect in FM/AFM Skyrmionic Structures Master Thesis under the supervision of Dr. Rembert Duine. In this master thesis, a square ferromagnetic and a square antiferromagnetic lattices are considered. WebYet, it is unknown how the topological properties are affected by magnon damping. We report the thermal Hall effect in Cr 2 Ge 2 Te 6, an insulating 2D honeycomb ferromagnet with a large Dirac magnon gap and significant magnon damping. Interestingly, the thermal Hall conductivity in Cr 2 Ge 2 Te 6 shows the

Web18 feb. 2014 · Abstract. Thermal Hall conductivity of magnons described by a noninteracting boson Hamiltonian is derived by the linear response theory. The thermal Hall … Webquantum Hall effect is a famous example, which results from placing a two-dimensional (2D) gas of electrons or quasiparticles in a large magnetic field [1]. Pioneering theoretical work by Haldane showed that some systems may inherently possess topological bands that allow them to exhibit quantum Hall physics without applied magnetic fields [2].
