Hexagonal α-Ru trichloride single crystals exhibit a strong magnetic anisotropy and we
show that upon applying fields up to 14 T in the honeycomb plane the successive magnetic …

We report our discovery of ferroelectricity in the spiral-magnetic state in the quantum quasi-
one-dimensional (1D) S= 1/2 magnet of LiCu 2 O 2. Electric polarization (P) emerges along …

Inelastic neutron scattering, susceptibility, and high-field magnetization identify LiCuVO 4 as
a nearest-neighbour ferromagnetic, next-nearest-neighbour frustrated, quasi–one …

The determination of anisotropic magnetic parameters is a task of both experimental and
theoretical interest. The added value of theoretical calculations can be crucial for analyzing …

Measurements of polarized neutron scattering were performed on a S= 1/2 chain multiferroic
LiCu 2 O 2. In the ferroelectric ground state with the spontaneous polarization along the c …

From thermodynamics, local spin density approximation+ Hubbard U studies and exact
diagonalizations of a five-band Hubbard model on CuO 2 stripes we find that Li 2 ZrCuO 4 …

We show by unbiased numerical calculations that the ferromagnetic nearest-neighbor
exchange interaction stabilizes a vector spin chiral order against the quantum fluctuation in …

The quasi-one-dimensional helimagnet Li Cu 2 O 2 was studied by single crystal inelastic
neutron scattering. The dispersion relation of spin wave excitations was measured in the …

We report a detailed examination of the magnetic structure of anhydrous cupric chloride
CuCl 2 carried out by powder neutron diffraction, magnetic susceptibility, and specific heat …

The application of first-principles methods to the study of complex-structured oxides,
primarily spinels and pyrochlores, is reviewed. The primary focus is on the crystal structure …
