Magnetodielectric coupling in Ca3Co2O6 triangular Ising lattice

Abstract : Geometric frustration in magnetic systems is a key ingredient for magnetodielectric coupling. Ca3Co2O6 system is a model of triangular Ising lattice and presenting exotic magnetic properties. With a partially disordered antiferromagnetic ground state and two steps in magnetisation to a ferrimagnetic state and to a ferromagnetic state, this oxide is a good system for studying the effect of frustration in magnetodielectric coupling. Dielectric constant measurements of single crystals of Ca3Co2O6 have been done showing the sensitivity of this technique to frustration.
