Extended Data Figure 4: Neutron diffraction of the (LuFeO3)6/(LuFe2O4)2 superlattice.
From: Atomically engineered ferroic layers yield a room-temperature magnetoelectric multiferroic
a, Magnetic reflections for the (LuFeO3)6/(LuFe2O4)2 superlattice were observed in neutron diffraction by scanning along the [10L] direction in reciprocal space at several temperatures between 5 K and 325 K. A single peak is observed showing considerable change in intensity between 5 K and room temperature. The offset from the 101 position is due to a slight misalignment of the sample. r.l.u. in a denotes reciprocal lattice units. b, Integrated intensity of the 101 magnetic reflection for the (LuFeO3)6/(LuFe2O4)2 superlattice as a function of temperature. The solid line is the mean-field fit. Error bars in a and b represent one standard deviation.
