Itinerant Antiferromagnetism in RuO
T. Berlijn, P. C. Snijders, O. Delaire +9
Bulk rutile RuO has long been considered a Pauli paramagnet. Here we report that RuO exhibits a hitherto undetected lattice distortion below approximately 900 K. The distor…
Ba8CoNb6O24: a spin-1/2 triangular-lattice Heisenberg antiferromagnet in the 2D limit
R. Rawl, L. Ge, H. Agrawal +11
The perovskite Ba8CoNb6O24 comprises equilateral effective spin-1/2 Co2+ triangular layers separated by six non-magnetic layers. Susceptibility, specific heat and neutron scatterin…
Ba2NiOsO6: A Dirac-Mott insulator with ferromagnetism near 100 K
Hai L. Feng, Stuart Calder, Madhav Prasad Ghimire +14
The ferromagnetic semiconductor Ba2NiOsO6 (Tmag ~100 K) was synthesized at 6 GPa and 1500 °C. It crystallizes into a double perovskite structure [Fm-3m; a = 8.0428(1) Å], where the…
Spin pseudogap in the chain material SrCuO with impurities
G. Simutis, S. Gvasaliya, N. S. Beesetty +14
The low energy magnetic excitation spectrum of the Heisenberg antiferromagnetic chain system SrCuO with Ni- and Ca-impurities is studied by neutron spectroscopy.…
The dynamics of linarite: Observations of magnetic excitations
K. C. Rule, B. Willenberg, M. Schäpers +9
Here we present inelastic neutron scattering measurements from the frustrated, quantum spin-1/2 chain material linarite, PbCuSO_4(OH)_2. Time of flight data, taken at 0.5K and zero…
Competing magnetic ground states and their coupling to the crystal lattice in CuFe2Ge2
Andrew F. May, Stuart Calder, David S. Parker +2
Identifying and characterizing systems with coupled and competing interactions is central to the development of physical models that can accurately describe and predict emergent be…
