Crossover of the high-energy spin fluctuations from collective triplons to localized magnetic excitations in doped Sr14-xCaxCu24O41 cuprate ladders
Y. Tseng, J. Thomas, W. Zhang +13
We studied the magnetic excitations in the quasi-one-dimensional (q-1D) ladder subsystem of Sr_(14-x) Ca_x Cu_24 O_41(SCCO) using Cu L_3-edge resonant inelastic X-ray scattering (R…
Suppression of Edge Localized Modes in ITER Baseline Scenario in EAST using Edge Localized Magnetic Perturbations
P. Xie, Y. Sun, M. Jia +31
We report the suppression of Type-I Edge Localized Modes (ELMs) in the EAST tokamak under ITER baseline conditions using Resonant Magnetic Perturbations (RMPs), while maint…
Effects of Ca substitution on quasi-acoustic sliding modes in SrCaCuO
E. Constable, A. D. Squires, J. Horvat +8
The low energy lattice dynamics of the quasi-periodic spin-ladder cuprate SrCaCuO are investigated using terahertz frequency synchrotron radiation. A hig…
Pseudospin-lattice coupling in the spin-orbit Mott insulator Sr2IrO4
J. Porras, J. Bertinshaw, H. Liu +15
Spin-orbit entangled magnetic dipoles, often referred to as pseudospins, provide a new avenue to explore novel magnetism inconceivable in the weak spin-orbit coupling limit, but th…
Incommensurate magnetic structure, Fe/Cu chemical disorder and magnetic interactions in the high-temperature multiferroic YBaCuFeO5
M. Morin, A. Scaramucci, M. Bartkowiak +9
Motivated by the recent observations of incommensurate magnetic order and electric polarization in YBaCuFeO5 up to temperatures TN2 as high as 230K [1,2] we report here for the fir…
Correlations and dynamics of spins in an XY-like spin-glass (Ni0.4Mn0.6)TiO3 single crystal system
R. S. Solanki, S. -H. Hsieh, C. H. Du +6
Elastic and inelastic neutron scattering (ENS and INS) experiments were performed on a single crystal of (Ni0.4Mn0.6)TiO3 (NMTO) to study the spatial correlations and dynamics of s…
