Abstract
- We investigate the magnetic and ferroelectric behaviors of 5d Ir<superscript>4+</superscript> substituted Mn<subscript>1−x</subscript>Ir<subscript>x</subscript>WO<subscript>4</subscript><subscript>+</subscript><subscript> δ</subscript> samples. The electric polarization is enhanced to a certain extent due to the Ir substitution of Mn. Furthermore, the non-polar AF1 phase is partially suppressed by the ferroelectric AF2 phase, resulting in the coexistence of the two phases below T<subscript>AF1</subscript>. It is suggested that the lattice distortion, the suppressed magnetic moment, and the increased Dzyaloshinskii–Moriya interaction are the key reasons for the enhanced polarization and the stabilized ferroelectric AF2 phase.
