Abstract	We present measurements of the magnetic field-induced microwave complex resistivity changes at 47 GHz in Tl2Ba2CaCu2O8+δ (TBCCO) thin films, in the ranges 58 K< T < Tc and 0< μ0H <0.8 T. The large imaginary part ∆ρ2(H) points to strong elastic response, but the data are not easily reconciled with a rigid vortex model. We find that, over a wide range of temperatures, all the pairs of curves ∆ρ1(H) and ∆ρ2(H) can be collapsed on a pair of scaling curves ∆ρ1[H/H ∗(T )], ∆ρ2[H/H ∗(T )], with the same scaling field H∗(T ). We argue that H∗(T ) is related to the loss of vortex rigidity due to a vortex transformation.
