With increasingtemperature, the magnitude of magnetic anisotropy, seen as a spin gap at the Brillouin zone center, decreasesin a power law fashion and vanishes at TC, while the in-plane and c-axis spin-wave stiffnesses associated withmagnetic exchange couplings remain robust at TC.We also compare parameter regimes where spin waves in CrI3can be described by a Heisenberg Hamiltonian with Dzyaloshinskii-Moriya interaction or a Heisenberg-KitaevHamiltonian. These results suggest that the SOC induced magnetic anisotropy plays a dominant role in stabilizingthe FM order in single layer 2D van der Waals ferromagnets.}, cin = {JCNS-FRM-II / JCNS-2 / MLZ}, ddc = {530}, cid = {I:(DE-Juel1)JCNS-FRM-II-20110218 / I:(DE-Juel1)JCNS-2-20110106 / I:(DE-588b)4597118-3}, pnm = {6G15 - FRM II / MLZ (POF3-6G15) / 6212 - Quantum Condensed Matter: Magnetism, Superconductivity (POF3-621) / 6G4 - Jülich Centre for Neutron Research (JCNS) (POF3-623)}, pid = {G:(DE-HGF)POF3-6G15 / G:(DE-HGF)POF3-6212 / G:(DE-HGF)POF3-6G4}, experiment = {EXP:(DE-MLZ)PANDA-20140101}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000525840300002}, doi = {10.1103/PhysRevB.101.134418}, url = {https://juser.fz-juelich.de/record/877883}, }
