TLDR
Inelastic neutron scattering, susceptibility, and high-field magnetization identify LiCuVO4 as a nearest-neighbour ferromagnetic, next-nearest-nighbour frustrated, quasi-one-dimensional helimagnet as discussed by the authors.Abstract:
Inelastic neutron scattering,susceptibility,and high-field magnetization identify LiCuVO4 as a nearest-neighbour ferromagnetic,next-nearest-neighbour frustrated,quasi-one- dimensional helimagnet,which is largely influenced by quantum fluctuations. Complementary band structure calculations provide a microscopic model with the correct sign and magnitude of the major exchange integrals.read more

Cupric oxide as an induced-multiferroic with high-TC.
TL;DR: It is proposed that copper(II) oxides (containing Cu2+ ions) having large magnetic superexchange interactions can be good candidates for induced-multiferroics with high Curie temperature (T(C), and ferroelectricity is demonstrated with T(C)=230 K in cupric oxide, CuO (tenorite), which is known as a starting material for the synthesis of high-T(c) (critical temperature) superconductors.

Unusual ordered phases of highly frustrated magnets: a review
TL;DR: In this paper, the authors review ground states and excitations of a quantum antiferromagnet on triangular and other frustrated lattices, and pay special attention to the combined effects of magnetic field h, spatial anisotropy R and spin magnitude S.

Emergent multipolar spin correlations in a fluctuating spiral: The frustrated ferromagnetic spin-1/2 Heisenberg chain in a magnetic field
TL;DR: In this article, the phase diagram of frustrated ferromagnetic S = 1/2 Heisenberg J(1)-J(2) chain in a magnetic field was obtained by large scale exact diagonalizations and density matrix renormalization group simulations.
