Magnetic phase transition induced by an electric field in coupled spin chains with magnetoelectric interaction

Abstract

Abstract A magnetization reversal and a magnetic phase transition induced by an electric field are studied in the coupled XY spin chains model with the next-nearest-neighbor, Dzyaloshinskii-Moriya ( S n x S n + 1 y - S n y S n + 1 x ) , and magnetoelectric ( S n x S n + 1 y - S n y S n + 1 x ) S n + 2 z interactions. Using the linear perturbation renormalization group recursion relations the phase diagram in the plane (temperature, electric field) is found. The phase transitions to two different low temperature phases and a reentrance behavior caused by the electric field are observed. At finite temperature for some range of the interchain interaction values in addition to changing the magnetization sign with reversal of the electric field, there is a possibility to the magnetization sign switch in finite electric field values with no applied magnetic field.
