Toroidal moment in the spin-glass system NixMn1-xTiO3 (x=0.42)
The discovery of spin-induced ferroelectricity in frustrated transition-metal-oxides attracted much interest due to their exciting physical mechanism and due to their potential applications. In most materials studied the magnetoelectric properties arecoupled with the so-called spin chirality via the inverse Dzyaloshinskii-Moriya interaction. Another multi-spin variable that couples directly with magnetoelectric properties is the toroidal moment which is given by the cross product between positions of the magnetic ions and their spins. So far the coupling between the multi-spin variables vector chirality and toroidal moment is studied in systems that exhibit long-range magnetic structure. However, very recently Yamaguchi et al. showed that long-range order actually is not needed. They find an antisymmetric finite magnetoelectric effect in a material that does not exhibit a long-range magnetic ordering. In Ni0.42Mn0.58TiO3 only a spin-glass ordering is observed that nevertheless seems to induce a linear magnetoelectric effect. The magnetic ordering in this material is however little characterized and we therefore wish to study it with neutron scattering methods.
