    Abstract

    Hexagonal ErFeO3 (h-ErFeO3) thin films were fabricated by a pulsed laser deposition method. X-ray diffraction experiments confirmed that singlephase h-ErFeO3 thin films were successfully obtained and were c axis-oriented. Ferroelectricity was confirmed by D-E hysteresis loop measurement at room temperature and the magnitude of spontaneous polarization was estimated to be 200 nC/cm2. A weak ferromagnetism appeared below 120K and dielectric constants started to exhibit magnetic field dependence. These observations demonstrate the coexistence of ferroelectricity and weak ferromagnetism in h-ErFeO3 thin films.
