Fig. 1: Temperature dependence of the magnetic satellites of EuAl4.
From: Spontaneous reversal of spin chirality and competing phases in the topological magnet EuAl4
Temperature dependence of (a) the integrated intensity and (b) the magnitude of the propagation vector along the h and k directions for the \({{{\boldsymbol{k}}}}_{{qq}}\), \({{{\boldsymbol{k}}}}_{q\bar{q}}\), \({{{\boldsymbol{k}}}}_{q0}^{2}\), \({{{\boldsymbol{k}}}}_{0q}^{2}\), \({{{\boldsymbol{k}}}}_{0q}^{3}\) \({and}\) \({{{\boldsymbol{k}}}}_{0q}^{4}\) magnetic satellites of the (0,0,8) reflection. c–f The magnetic satellites of the (0,0,8) reflection shown in the (h k 0) plane for each of the magnetically ordered phases, where the intensity of the magnetic satellites is represented by the size of the circular markers plotted according to a logarithmic scale. The (0,0,8) reflection is also shown for reference. The black crosses indicate the expected position of the magnetic satellite based on the experimentally measured position of the corresponding +k satellite. g–i Line cuts of the magnetic satellites measured about the (0,0,8) reflection at various temperatures. We note that this data was collected at a position in the sample where the \({{{\boldsymbol{k}}}}_{q0}^{3}\) \({and}\) \({{{\boldsymbol{k}}}}_{q0}^{4}\) magnetic satellites were not present. Data for each of the magnetic satellites is given in a different colour for clarity and ease of data interpretation; red for \({{{\boldsymbol{k}}}}_{{qq}}\), orange for \({{{\boldsymbol{k}}}}_{q\bar{q}}\), purple for \({{{\boldsymbol{k}}}}_{q0}^{2}\), blue for \({{{\boldsymbol{k}}}}_{0q}^{2}\), green for \({{{\boldsymbol{k}}}}_{0q}^{3}\) and black for \({{{\boldsymbol{k}}}}_{0q}^{4}\) magnetic satellite.
