Fig. 4: Characterization of Mn5Si3 single crystals.
From: Anomalous Nernst effect in the noncollinear antiferromagnet Mn5Si3
Laue diffraction patterns of a Mn5Si3 single crystal oriented with the x-ray beam along the a [001] and b [210] directions of the hexagonal structure at room temperature. At T < 100 K, the [100], [210], and [001] directions correspond to the a, b, and c axes, respectively, of the orthorhombic phase. c Temperature difference ΔT = Th − Tc between the hot and the cold end of the sample vs heater power for different average temperatures T0. Solid lines indicate a linear behavior. Inset shows a cartoon of the experimental set up and the orientation of the sample with crystallographic axes a, b, and c of low-temperature orthorhombic phase with respect to the sample holder.
