Structures of magnetic excitations in the spin-1/2 kagome-lattice antiferromagnets CsCuSnF and RbCuSnF
Mutsuki Saito, Ryunosuke Takagishi, Nobuyuki Kurita +6
We show the structures of magnetic excitations in spin-1/2 kagome-lattice antiferromagnets CsCuSnF and RbCuSnF investigated by inelastic neutron scatt…
Magnons and Spinons in : A Composite System of Isolated Spin- Triangular Heisenberg-like and Frustrated Honeycomb Ising-like Antiferromagnets
Yuki Kojima, Nobuyuki Kurita, Hidekazu Tanaka +1
We report the neutron scattering results on magnetic orderings and excitations in composed of two almost isolated subsystems A and B, which are desc…
Continuous control of classical-quantum crossover by external high pressure in the coupled chain compound CsCuCl
Daisuke Yamamoto, Takahiro Sakurai, Ryosuke Okuto +4
In solid materials, the parameters relevant to quantum effects, such as the spin quantum number, are basically determined and fixed at the chemical synthesis, which makes it challe…
First ESR Detection of Higgs Amplitude Mode and Analysis with Extended Spin-Wave Theory in Dimer System KCuCl
Masashige Matsumoto, Takahiro Sakurai, Yuki Hirao +3
KCuCl is known to show a quantum phase transition from the disordered to antiferromagnetically ordered phases by applying pressure. There is a longitudinal excitation mode (Hig…
