Multiple Magnetic Bilayers and Unconventional Criticality without Frustration in BaCuSiO

S. Allenspach, A. Biffin, U. Stuhr +9

The dimerized quantum magnet BaCuSiO was proposed as an example of "dimensional reduction" arising near the magnetic-field-induced quantum critical point (QCP) due to perfe…

Dynamical structure factors and excitation modes of the bilayer Heisenberg model

M. Lohöfer, T. Coletta, D. G. Joshi +4

Using quantum Monte Carlo simulations along with higher-order spin-wave theory, bond-operator and strong-coupling expansions, we analyse the dynamical spin structure factor of the…

Evidence of quantum dimer excitations in SrIrO

M. Moretti Sala, V. Schnells, S. Boseggia +12

The magnetic excitation spectrum in the bilayer iridate SrIrO has been investigated using high-resolution resonant inelastic x-ray scattering (RIXS) performed at the ir…

Quantum stabilization of classically unstable plateau structures

T. Coletta, M. E. Zhitomirsky, F. Mila

Motivated by the intriguing report, in some frustrated quantum antiferromagnets, of magnetization plateaus whose simple collinear structure is {\it not} stabilized by an external m…

Destruction of valence-bond order in a sawtooth chain with a Dzyaloshinskii-Moriya term

Zhihao Hao, Yuan Wan, Ioannis Rousochatzakis +4

A small value of the spin gap in quantum antiferromagnets with strong frustration makes them susceptible to nominally small deviations from the ideal Heisenberg model. One of such…

Ferrimagnetism of the magnetoelectric compound CuOSeO probed by Se NMR

M. Belesi, I. Rousochatzakis, H. C. Wu +4

We present a thorough Se NMR study of a single crystal of the magnetoelectric compound CuOSeO. The temperature dependence of the local electronic moments extracted f…
