Abstract

The magnetism-induced ferroelectricity in the E -type orthorhombic HoMn O ₃ (o -HMO) films grown on Nb-doped and undoped SrTi O ₃ (001) substrates was studied. The temperature dependent magnetization in these films evidently exhibits an antiferromagnetic ordering around 44 K and an anomalous second magnetic ordering along the c -axis near 35 K. Interestingly, at this anomalous transition temperature, an associated ferroelectric polarization was probed by the P-E hysteresis measurements, indicating the intimated coupling between the ferroelectric response and the reordering of Mn spins, which has never been disclosed previously by dielectric constant measurements.
