摘要：

Magnetic critical current density was measured at various temperatures and fields for SmBa2Cu3O7-x single crystal. Pronounced second peaks were observed at intermediate fields and temperatures. Normalized pinning force density f(p) = F-p/F-p, (max) exhibited a clear scaling law when H was normalized by H-max where the pinning force density has the maximum value. This is an indication that a single pinning mechanism exists in the investigated temperature region.
