Directional magnetoelectric effects in MnWO4: magnetic sources of the electric polarization
P. Toledano, B. Mettout, W. Schranz +1
The ferroelectric order and magnetic field induced effects observed in the spiral phase of MnWO4 are described theoretically. It is demonstrated explicitly that the Dzyaloshinskii-…
Monte Carlo Minimization of the Higgs-Landau Potentials
Jai Sam Kim, J. C. Toledano, P. Toledano
We propose a Monte Carlo algorithm to search for the boundary points of the orbit space which is important in determining the symmetry breaking directions in the Higgs potential an…
Helical magnetic state in the distorted triangular lattice of alpha-CaCr2O4
L. C. Chapon, P. Manuel, F. Damay +3
The magnetic properties of the high temperature alpha form of the CaCr2O4 compound have been investigated for the first time by magnetic susceptibility, specific heat and powder ne…
Incommensurate spin-density wave and magnetic lock-in transition in CaFe4As3
P. Manuel, L. C. Chapon, I. S. Todorov +6
The magnetic structure for the newly discovered iron-arsenide compound \CaFeAs has been studied by neutron powder diffraction. Long-range magnetic order is detected below 85K, with…
Induced ferroelectric phases in TbMn_2O_5
P. Toledano, W. Schranz, G. Krexner
The magnetostructural transitions and magnetoelectric effects reported in TbMn2O5 are described theoretically and shown to correspond to two essentially different mechanisms for th…
