Multiferroic Sc-doped YFeO₃ nanoparticles were obtained by a low-temperature solid-state reaction route. It
indicated that with the addition of Sc, nanosized YFeO₃ powders were obtained at 800 ^oC, and the orthorhombic
phase was transformed into the hexagonal structure. Magnetic hysteresis loop illustrated the magnetic
property of YFeO₃ nanoparticles improved with Sc doping. The maximum magnetization of the powders was
about 4.00 emu/g, showing that the energy gap can be reduced to 2.25 eV and thus the doping nanoparticles
can be used in optical field. Therefore, the optical and magnetic properties of the material can be obviously
enhanced with Sc doping, proving its potential application in magnetic and optical fields.
