✦ Synopsis

We present results of the determination of the lower critical magnetic fields: Josephson He1 J, nc2 J and Abrikosov Hcl J type for the Y-123 and Bi-2212 layers onto MgO substrate. Based on the DC magnetic field dependence of the real part Z" of complex AC susceptibility we assumed that He1J = 3.10e and He2 J = 11.40e for Y-layer and He2 J = 4.50e and Helg = 16.30e for Bi-layer.
