Spin texture induced by non-magnetic doping and spin dynamics in 2D triangular lattice antiferromagnet h-Y(Mn,Al)O3
Pyeongjae Park, Kisoo Park, Joosung Oh +14
Novel effects induced by nonmagnetic impurities in frustrated magnets and quantum spin liquid represent a highly nontrivial and interesting problem. A theoretical proposal of exten…
Spontaneous decays of magneto-elastic excitations in noncollinear antiferromagnet (Y,Lu)MnO3
Joosung Oh, Manh Duc Le, Ho-Hyun Nahm +12
When magnons and phonons, the fundamental quasiparticles of the solid, are coupled to one another, they form a new hybrid quasi-particle, leading to novel phenomena and interesting…
Magnon breakdown in a two dimensional triangular lattice Heisenberg antiferromagnet of multiferroic LuMnO
Joosung Oh, Manh Duc Le, Jaehong Jeong +7
The breakdown of magnons, the quasiparticles of magnetic systems, has rarely been seen. By using an inelastic neutron scattering technique we report the observation of spontaneous…
Magnetic Excitations and their energy change available to Superconducting Condensation in Optimally Doped YBaCuO
Hyungje Woo, Pengcheng Dai, S. M. Hayden +5
Understanding the magnetic excitations in high-transition temperature (high-) copper oxides is important because they may mediate the electron pairing for superconductivity. B…
High Energy Spin Excitations in Electron-Doped Superconducting PrLaCeCuO with K
Stephen D. Wilson, Shiliang Li, H. Woo +5
We use high-resolution inelastic neutron scattering to study the low-temperature magnetic excitations of electron-doped superconducting PrLaCeCuO ($T_c=21…
Universal magnetic excitation spectrum in cuprates
J. M. Tranquada, H. Woo, T. G. Perring +5
We have recently used inelastic neutron scattering to measure the magnetic excitation spectrum of La(1.875)Ba(0.125)CuO(4) up to 200 meV. This particular cuprate is of interest bec…
