    • Abstract

       

      YCrO$_3$ nanoparticles were prepared by reverse micellar method by the use of surfactant tergitol after heating theprecursor sample at 800$^{\circ}$C. As-prepared YCrO$_3$ nanoparticles were characterized by various sophisticated techniques like X-ray diffraction (XRD), transmission electron microscope, Brunauer–Emmett–Teller surface area analyzer, high frequency LCR-meter, superconducting quantum interface device magnetometer and P–E loop tracer. Powder XRD study revealsthe formation of highly crystalline orthorhombic monophasic YCrO$_3$ nanoparticles. The average grain size of as-preparednanoparticles was found to be 35 nm with the surface area of 348 m$^2$ g$^{−1}$.Wedge-shaped hysteresis for ferromagnetism andthe room temperature ferroelectricity confirm the multiferroic characteristics in the nanoparticles.
