Magnetoelectric coupling in the multiferroic compound LiCu2O2
We investigate the possible types of coupling between ferroelectricity and magnetism for the zigzag spin chain multiferroic compound LiCu2O2. We construct a multi-order-parameter phenomenological model for the material based on a group theoretical analysis. We find that a theory involving interchain magnetoelectric coupling belonging to the same unit cell explains the experimental results of Pa...
متن کاملMagnetic ground state and transition of a quantum multiferroic LiCu2O2.
Based on resonant soft x-ray magnetic scattering, we report that LiCu2O2 exhibits a large interchain coupling which suppresses quantum fluctuations along spin chains, and a quasi-2D short-range magnetic order prevails at temperatures above the magnetic transition. These observations unravel the fact that the ground state of LiCu2O2 possesses long-range 2D-like incommensurate magnetic order rath...
متن کاملThermodynamic properties of the new multiferroic material ( NH 4 ) 2
(NH4)2[FeCl5(H2O)], a member of the family of antiferromagnetic A2[FeX5(H2O)] compounds (X = halide ion and A = alkali metal or ammonium ion) is classified as a new multiferroic material. We report the onset of ferroelectricity below '6.9K within an antiferromagnetically ordered state (TN ' 7.25K). The corresponding electric polarization can drastically be influenced by applying magnetic fields...
متن کاملMagnetic Phase Transitions in the double spin-chains compound LiCu2O2
We report high-resolution x-ray diffraction, muon-spin-rotation spectroscopic and specific heat measurements in the double spin-chains compound LiCu2O2. The x-ray diffraction results show that the crystal structure of LiCu2O2 is orthorhombic down to T=10K. Anisotropic 1 line-broadening of the diffraction peaks is observed, indicating disorder along the spin chains. Muon spin relaxation and spec...
