According to recent neutron diffraction and small-angle neutron scattering experiments,^A1,A2 the magnetic ordering at x = 0 (CaMn₇O₁₂) is modulated, with a temperature-dependent modulation wave vector (k). The peak at T = 48–49 K, visible in our Fig. 7, and also in the ac susceptibility data of ref. A3, is associated with the abrupt change in the magnitude of k. We are grateful to Dr. I. Sosnowska and Dr. R. Przenioslo for bringing this point to our attention.
