Fermi surface of IrTe2 in the valence-bond state as determined by quantum oscillations

S. F. Blake, M. D. Watson, A. McCollam +11

We report the observation of the de Haas-van Alphen effect in IrTe2 measured using torque magnetometry at low temperatures down to 0.4 K and in high magnetic fields up to 33T. IrTe…

Unconventional magnetic order on the hyperhoneycomb Kitaev lattice in -Li2IrO3: full solution via magnetic resonant x-ray diffraction

A. Biffin, R. D. Johnson, Sungkyun Choi +6

The recently-synthesized iridate -LiIrO has been proposed as a candidate to display novel magnetic behavior stabilized by frustration effects from bond-dependent, anisot…

Non-coplanar and counter-rotating incommensurate magnetic order stabilized by Kitaev interactions in -Li2IrO3

A. Biffin, R. D. Johnson, I. Kimchi +5

Materials that realize Kitaev spin models with bond-dependent anisotropic interactions have long been searched for, as the resulting frustration effects are predicted to stabilize…

First-principles study of multiferroic RbFe(MoO)

Kun Cao, R. D. Johnson, Feliciano Giustino +3

We have investigated the magnetic structure and ferroelectricity in RbFe(MoO) via first-principles calculations. Phenomenological analyses have shown that ferroelectricity…

CaBaCoO : A ferrimagnetic pyroelectric

R. D. Johnson, K. Cao, P. G. Radaelli

Magneto-electric coupling in pyroelectric CaBaCoO is investigated using ab-intio calculations and Landau theory. The former shows that exchange-striction is strong enough t…
