Magnetic and thermodynamic properties and spin-flop-driven magnetodielectric response of the antiferromagnetic Pb2Fe2Ge2O9 single crystals
Journal of Magnetism and Magnetic Materials(2019)
Abstract
•Pb2Fe2Ge2O9 single crystals were grown using a pseudo-flux technique.•Weak ferromagnetism arises due to single-ion anisotropy and Dzyaloshinskii–Moria mechanisms.•The principal magnetic anisotropy directions coincide with the orthorhombic axes.•Most prominent magnetodielectric response was observed in Pb2Fe2Ge2O9 at the spin-flop transition.
