    • 3 layers in this system (Ref. 12). Our crystal also has a secondary ferromagnetic transition at 250 K presumably due to the intergrowth. However, the relative magnetization was less than 0.6%, a too small value to account for more than the 50% reduction in ZFC magnetization at low temperatures

    • Such frequency dependencies can be observed also in superparamagnetic materials. However, superparamagnetism (due to noninteracting collection of magnetically ordered clusters) is not expected in (strongly correlated) metallic single crystal samples like the one we are discussing now

    • We assume that doping corresponds to the part of the phase diagram, in which the ordered state is a ferromagnet. At a different doping, the high temperature transition can be the antiferromagnet-to-paramagnet transition, and the low temperature transition will then be the antiferromagnet-to-canted-phase transition

    • Even though single-site mean field calculation with relevant parameters points to the canted phase, the authors of Ref. 8 noted that the real system might possess more complicated spin ordering like spin glasses
