Abstract
Strong magnetoelectric (ME) coupling has been one of the dreaming goals in magnetoelectric and multiferroic materials. In particular, the electro-control of magnetic ordering and magnetization is of high interest. In this work, we synthesize NdCrTiO5 and perform a set of characterization studies on the multiferroic properties and the linear ME effect. It is revealed that NdCrTiO5 exhibits a magnetic phase transition at TN ∼ 20 K, below which a remarkable ME response is observed. On one hand, it is non-ferroelectric at zero magnetic field and a magnetic field as low as 1.0 T is sufficient to induce remarkable pyroelectric current below TN, demonstrating the magnetism-induced ferroelectricity. On the other hand, the remarkable magnetic control of electric polarization and electro-control of magnetization are recorded. At 10 K, a magnetic field of 1.0 T can lead to a change in polarization as large as 20%. Moreover, magnetization M can be significantly modulated by an electric field, with the estimated inverse ME coefficient as large as −1.84 ps/m. The temporal evolution of electrical polarization and magnetization indicates the stable ME mutual control, suggesting potential applications of NdCrTiO5 as a promising multiferroic.
