(Left) Rietveld refinement results of the neutron diffraction patterns of (a) AFM Au65Ga21Tb14 1/1 PA (TN = 13.2 K) and (c) FM Au60Ga26Tb14 1/1 PA (Tc = 15.5 K) measured at base temperature. The observed intensities, calculated intensities and their difference are shown as black dots, red curves and blue curves, respectively. The positions of the nuclear reflections, aluminium reflections from the sample holder and magnetic reflections are indicated by black, blue and red vertical solid lines, respectively. (Right) Schematic representations of (b) the whirling AFM order in Au65Ga21Tb14 and (d) the whirling FM order in Au60Ga26Tb14 1/1 PA, showing two adjacent icosahedron clusters within the cubic unit cell, viewed along the [100] crystallographic direction.
