The magnetic Hamiltonian and phase diagram of the quantum spin liquid Ca10Cr7O28
Christian Balz, Bella Lake, A. T. M. Nazmul Islam +6
A spin liquid is a new state of matter with topological order where the spin moments continue to fluctuate coherently down to the lowest temperatures rather than develop static lon…
Impurity effects on spin dynamics in magnetic and superconducting iron pnictides and chalcogenides
M. A. Surmach, P. Y. Portnichenko, J. T. Park +5
In this paper we summarize the effects of magnetic and nonmagnetic impurities on the spin dynamics in Febased superconductors and their parent compounds. The effects of chemical su…
Physical realization of a quantum spin liquid based on a novel frustration mechanism
Christian Balz, Bella Lake, Johannes Reuther +11
Unlike conventional magnets where the magnetic moments are partially or completely static in the ground state, in a quantum spin liquid they remain in collective motion down to the…
Modulated magnetism and anomalous electronic transport in
Jiakui K. Wang, Shan Wu, Yiming Qiu +4
The complex magnetism and transport properties of tetragonal CeCuAsO were examined through neutron scattering and physical properties measurements on polycrystallin…
Solitary magnons in the antiferromagnet CaFeO
C. Stock, E. E. Rodriguez, N. Lee +10
CaFeO is a anisotropic antiferromagnet based upon zig-zag chains having two competing magnetic structures, denoted as the A ($\uparrow \uparrow \downarro…
Antiferromagnetic and Orbital Ordering on a Diamond Lattice Near Quantum Criticality
K. W. Plumb, Jennifer Morey, J. A. Rodriguez-Rivera +4
We present neutron scattering measurements on powder samples of the spinel FeSc2S4 that reveal a previously unobserved magnetic ordering transition occurring at 11.8(2)~K. Magnetic…
