Discovery of coexisting Dirac and triply degenerate magnons in a three-dimensional antiferromagnet
Song Bao, Jinghui Wang, Wei Wang +11
Topological magnons are emergent quantum spin excitations featured by magnon bands crossing linearly at the points dubbed nodes, analogous to fermions in topological electronic sys…
Spin dynamics near a putative antiferromagnetic quantum critical point in Cu substituted BaFeAs and its relation to high-temperature superconductivity
M. G. Kim, M. Wang, G. S. Tucker +15
We present the results of elastic and inelastic neutron scattering measurements on non-superconducting Ba(FeCu)As, a composition close to a quan…
Magnon spectrum of the helimagnetic insulator Cu2OSeO3
P. Y. Portnichenko, J. Romhanyi, Y. A. Onykiienko +11
Complex low-temperature ordered states in chiral magnets are typically governed by a competition between multiple magnetic interactions. The chiral-lattice multiferroic Cu2OSeO3 be…
Direct observation of dynamic charge stripes in La2-xSrxNiO4
S. Anissimova, D. Parshall, G. D. Gu +8
The insulator-to-metal transition continues to be a challenging subject, especially when electronic correlations are strong. In layered compounds, such as La2-xSrxNiO4 and La2-xBax…
