Disorder-induced magnetism in the magnetically fructrated A-site spinel CoAl2O41 Supplemental Information Phase transitions and slow spin dynamics of slightly inverted A-site spinel CoAl2−xGaxO4  T. Naka, J. Valenta, T. Nakane, S. Ishii, M. Nakayama, H. Mamiya, K. Takehana, N. Tsujii Y. Imanaka, Y. Matsushita, H. Abe, T. Uchikoshi, and H. Yusa   Crystallographic analysis  FIG. S1. XRD profiles for CoAl2−xGaxO4 obtained with a monochromatic synchrotron x-ray source with wavelengths of 0.65298 Å for 0  x  1.2 and 0.620089 Å for 1.4  x  2.0.   2 Table S-I. Crystallographic parameters for CoAl2−xGaxO4 refined with the Rietveld method.a   aThe cationic configuration was refined with the confinements gA(Co) = 1 − gA(Al) − gA(Ga), gB(Co) = [gA(Al) + gA(Ga)]/2, gB(Al) = 1 − [x + gA(Al)]/2, and gB(Ga) = [x − gA(Ga)]/2. Note that,  = 1 − gA(Co). Data points for x = 0 and = 2.0 are from previous studies [9] and [5], respectively.   3  FIG. S2. XRD profiles for CoAl2−xGaxO4 obtained with a monochromatic synchrotron x-ray source with a wavelength of 0.65296 Å for 0.02  x  0.30.   Fig. S3. A-site occupancy of Ga ions gA(Ga) for x < 0.8. Solid line corresponds to gA(Ga) = mx. The constant m = 0.56(1) was obtained by least squares. 4 Table S-II. Crystallographic parameters for CoAl2−xGaxO4 in the range 0.01  x  0.10, refined with the Rietveld method.b  bThe x-variation of gA(Ga) was assumed to be gA(Ga) = 0.56x in the range 0.02  x  0.10 (See Fig. S3).    Fig. S4. Inversion parameter  as a function of x (for x  0.2) obtained on the assumption that gA(Ga) = 0.56x. Dashed line represents the polynomial curve (x) = K0 + K1x + K2x2 that was obtained by least squares, with K0 = 0.0560(7), K1 = 0.37(2), and K2 = 0.55(9). From the polynomial of (x), we determined that  = 0.060(2), 0.076(1), and 0.089(2) for x = 0.01, 0.05, and 0.08, respectively.
