Probing magnon dynamics and interactions in a ferromagnetic spin-1 chain
Prashant Chauhan, Fahad Mahmood, Hitesh J. Changlani +2
NiNbO is an almost ideal realization of a 1D spin-1 ferromagnetic Heisenberg chain compound with weak unidirectional anisotropy. Using time-domain THz spectroscopy, we…
Synthesis, crystal growth and characterization of the pyrochlore Er2Ti2O7
Q. Wang, A. Ghasemi, A. Scheie +1
Pyrochlore erbium titanate samples in the form of powders (with nominal compositions of Er2Ti2+xO7) and bulk single crystals were prepared to elucidate the effect of synthesis and…
Magnetic excitations of the classical spin liquid MgCr2O4
X. Bai, J. A. M. Paddison, E. Kapit +9
We report a comprehensive inelastic neutron-scattering study of the frustrated pyrochlore antiferromagnet MgCr2O4 in its cooperative paramagnetic regime. Theoretical modeling yield…
Non-uniform carrier density in CdAs evidenced by optical spectroscopy
I. Crassee, E. Martino, C. C. Homes +13
We report the detailed optical properties of CdAs crystals in a wide parameter space: temperature, magnetic field, carrier concentration and crystal orientation. We investi…
Anomalous 3D bulk AC conduction within the Kondo gap of SmB single crystals
N. J. Laurita, C. M. Morris, S. M. Koohpayeh +5
The Kondo insulator SmB has long been known to display anomalous transport behavior at low temperatures, T K. In this temperatures range, a plateau is observed in the dc re…
Magneto-optical signature of massless Kane electrons in Cd3As2
A. Akrap, M. Hakl, S. Tchoumakov +21
We report on optical reflectivity experiments performed on Cd3As2 over a broad range of photon energies and magnetic fields. The observed response clearly indicates the presence of…
Interaction Driven Subgap Spin Exciton in the Kondo Insulator SmB6
W. T. Fuhrman, J. Leiner, P. Nikolić +12
Using inelastic neutron scattering, we map a 14 meV coherent resonant mode in the topological Kondo insulator SmB6 and describe its relation to the low energy insulating band struc…
Disorder from order among anisotropic next-nearest-neighbor Ising spin chains in SrHoO
J. -J. Wen, W. Tian, V. O. Garlea +7
We describe why Ising spin chains with competing interactions in segregate into ordered and disordered ensembles at low temperatures (). Using elastic neutron sc…
A hierarchy of bound states in the 1D ferromagnetic Ising chain CoNbO investigated by high resolution time-domain terahertz spectroscopy
C. M. Morris, R. Valdés Aguilar, A. Ghosh +6
Kink bound states in the one dimensional ferromagnetic Ising chain compound CoNbO have been studied using high resolution time-domain terahertz spectroscopy in zero applied…
