โœฆ Synopsis

Lower critical fields parallel and perpendicular to the layers of the superconducting Nb(2OO~4)/Cu(150~4) multilayer were measured in the temperature range from Tc = 7.2K down to 2K.

The anisotropy of the lower critical field for the S/N multilayer was obtained for the first time. The anisotropy exhibited a sharp upturn at T ,-~ 5.5K. This temperature was found to coincide with the temperature of 3D-2D crossover obtained from the measurements of the upper critical field.

## Measurements of the critical current J, have been made for the Nb/Nb,&,, multilayer which showed a sharp upturn behavior in a parallel upper critical field W,,,,(T), caused by the shift of the order-parameter A(r) from Nb-to NbZr-layers. In the region where A(r) is localized in the Nb-layers,

The anisotropy of the first critical field Hcl is found to increase from H/c/~(0)/H~I(0)=4 to I0 on going to x=0.93 llc to. x=0.64 . For x=0.93, Hcl(0)=(950-+200)Oe, Hc1~( 0)=(230+20)Oe. For x=0.64, H/~(0)=(270-+30)Oe, .LC + Hc1(0)=(27-2)Oe. An anomalous linear T-dependence was found for H//c at low
