The susceptibility x = x′ + ix″ of RuSr2GdCu2O8 powders at 2 K has been deduced from ac and dc magnetizations with their particle size d from 800 to 10 μm and grain size 1-5 μm. It is observed that the loss part, x″, scales with d over a field range of 0.0001 to 100 Oe, suggesting that the supercurrent is homogeneously distributed over particles as small as 10 μm. However, the inductance part, x′, decreases with d systematically and drastically. An effective penetration depth as large as 30-50 μm is needed, which suggests a very small super-carrier concentration. Crypto-superconductivity is proposed to accommodate the data.
