Abstract

In spite of its frustrated lattice, the multiferroic Lu0.5Sc0.5FeO3 exhibits two consecutive magnetic transitions at TN1 ≈ 175 K and TN2 ≈ 70 K determined from neutron diffraction. In the ordered state, magnetic fluctuations are present, most likely arising from the in-plane frustrated interaction of the Fe hexagonal lattice. Furthermore, a crossover of the magnetic intensity is observed from elastic to inelastic upon warming, indicating that magnetic fluctuations persist well above TN1, a common feature in hexagonal multiferroics.
