Abstract
We investigate the structural, magnetic, and magnetoelectric properties of DyCr0.5Mn0.5O3. DyCr0.5Mn0.5O3 exhibits ferroelectricity at the paramagnetic–antiferromagnetic transition temperature, i.e., TN = 74 K, demonstrating the polarization is driven by magnetic order. Furthermore, the ferroelectric polarization can be substantially influenced by applied magnetic fields indicating a strong magnetoelectric effect in DyCr0.5Mn0.5O3. It is demonstrated that the ferroelectricity in DyCr0.5Mn0.5O3 may stem from the spin-phonon coupling of Dy and Mn/Cr ions as evidenced by the temperature dependence of Raman phonon modes. The results manifest that DyCr0.5Mn0.5O3 is a potential candidate for magnetoelectric device applications.
