Title: Magnetic field induced changes in the critical exponent {beta} of the chiral triangular antiferromagnet CsMnBr{sub 3} in the presence of an electric field (abstract)

Abstract

The magnetic moments in the triangular antiferromagnetic CsMnBr{sub 3} order at T{sub N}=8.3 K with a frustration of the magnetic moments in a 120{degree} type magnetic structure. The magnetic moments are either ordered in a clockwise or an anticlockwise direction resulting in a chirality ordering, which is characterized by the critical exponent of the magnetic sublattice magnetization {beta}=0.25. It has been shown that an electric field applied along the [110] direction removes the chiral ordering and a linear Ising-like phase will be established; consequently, the value of {beta} decreases. The subsequent application of a magnetic field of B=4 T along the [100] direction causes the critical exponent {beta} to increase. The magnetic phase diagram of CsMnBr{sub 3} does not change due to the introduction of an electric field.{copyright} {ital 1997 American Institute of Physics.}
