Noncollinear magnetic structure and magnetoelectric coupling in buckled honeycomb CoNbO:A single crystal neutron diffraction study
Lei Ding, Minseong Lee, Tao Hong +8
Through analysis of single crystal neutron diffraction data, we present the magnetic structures of magnetoelectric Co4Nb2O9 under various magnetic fields. In zero-field, neutron di…
Direct observation of the Higgs amplitude mode in a two-dimensional quantum antiferromagnet near the quantum critical point
Tao Hong, Masashige Matsumoto, Yiming Qiu +12
Spontaneous symmetry-breaking quantum phase transitions play an essential role in condensed matter physics. The collective excitations in the broken-symmetry phase near the quantum…
Ba8CoNb6O24: a spin-1/2 triangular-lattice Heisenberg antiferromagnet in the 2D limit
R. Rawl, L. Ge, H. Agrawal +11
The perovskite Ba8CoNb6O24 comprises equilateral effective spin-1/2 Co2+ triangular layers separated by six non-magnetic layers. Susceptibility, specific heat and neutron scatterin…
Field induced spontaneous quasiparticle decay and renormalization of quasiparticle dispersion in a quantum antiferromagnet
Tao Hong, Y. Qiu, M. Matsumoto +7
The notion of a quasiparticle, such as a phonon, a roton, or a magnon, is used in modern condensed matter physics to describe an elementary collective excitation. The intrinsic zer…
Spin-lattice coupling mediated multiferroicity in (ND4)2FeCl5D2O
W. Tian, Huibo Cao, Jincheng Wang +9
We report a neutron diffraction study of the multiferroic mechanism in (ND4)2FeCl5D2O, a molecular compound that exhibits magnetically induced ferroelectricity. This material exhib…
