Giant shifts of crystal-field excitations with temperature as consequence of internal magnetic exchange fields
Joel O'Brien, Guochu Deng, Dehong Yu +7
Crystal-field excitations, for example in transition-metal oxides where a rare-earth element is used as a spacer between the transition-metal-oxide tetrahedra and octahedra, are as…
Competing magnetic orders in quantum critical SrRuO
A. Putatunda, G. Qin, W. Ren +1
We investigated SrRuO, a quantum critical metal that shows a metamagnetic quantum phase transition and electronic nematicity, through density functional calculations. T…
Insulator-metal transition and quasi-flat-band of Shastry-Sutherland lattice
Huai-Xiang Huang, Jing Chen, Wei Ren +3
Insulator-metal transition is investigated self-consistently on the frustrated Shastry-Sutherland lattice in the framework of Slave-Boson mean-field theory. Due to the presence of…
Spin dynamics of edge-sharing spin chains in SrCa13Cu24O41
Guochu Deng, Dehong Yu, Richard Mole +14
The low-energy magnetic excitation from the highly Ca-doped quasi-one-dimensional magnet SrCa13Cu24O41 was studied in the magnetic ordered state by using inelastic neutron scatteri…
