Abstract: Different χac measurements can be collapsed into a single curve if plotted against the ac penetration depth δ = h/Jd. Further, using this scaling law, it is possible to obtain the frequency dependence of the shielding current density J(ν, B, T). In this work, this scaling relation was tested for a Er Ba2Ou3O7-δ single crystal. The frequency dependence of J(ν, B, T) displays a behavior closely related with the second magnetization peak ("fishtail effect") observed in M × H curves. This result supports a dynamical interpretation for the fihtail effect. © 2000 Elsevier Science B.V. All rights reserved.
