Abstract
We report on the growth of stoichiometric, single-crystal YCrO3 epitaxial thin films on (001) SrTiO3 substrates using pulsed laser deposition. X-ray diffraction and atomic force microscopy reveal that the films grew in a layer-by-layer fashion with excellent crystallinity and atomically smooth surfaces. Magnetization measurements demonstrate that the material is ferromagnetic below 144 K. The temperature dependence of dielectric permittivity shows a characteristic relaxor-ferroelectric behavior at TC = 375–408 K. A dielectric anomaly at the magnetic transition temperature indicates a close correlation between magnetic and electric order parameters in these multiferroic YCrO3 films. These findings provide guidance to synthesize rare-earth, chromite-based multifunctional heterostructures and build a foundation for future studies on the understanding of magnetoelectric effects in similar material systems.
Highlights
Magnetoelectric multiferroics have emerged as an attractive material system due to their multifunctionality for a variety of potential device applications in energy and memory technologies [1,2,3]
We report on the epitaxial growth and physical properties of stoichiometric, multiferroic YCO films, which shows both relaxor-ferroelectric and ferromagnetic orders coexisting in the thin film
We show that the highly crystalline, phase-pure epitaxial YCO thin films can be grown on (001) SrTiO3 (STO) substrates using Pulsed laser deposition (PLD), avoiding any post-synthesis annealing steps
