| 摘 要： | As one of the most promising Kitaev quantum-spin-liquid（QSL） candidates,α-RuCl3 has received a great deal of attention.However,its ground state exhibits a long-range zigzag magnetic order,which defies the QSL phase.Nevertheless,the magnetic order is fragile and can be completely suppressed by applying an external magnetic field.Here,we explore the evolution of magnetic excitations of α-RuCl3 under an in-plane magnetic field,by carrying out inelastic neutron scattering measu...
