Magnetically Dependent Superconducting Transport in Oxide Heterostructures with an Antiferromagnetic Layer

Kislinskiǐ, Yu V.National Research University of Electronic Technology (MIET) (author)

The superconducting current in hybrid superconducting structuresNb/Au/Ca1−xSrxCuO2/YBa2Cu3O7 –δwith an antiferromagnetic layer is experimentally shown to have aJosephson nature, and the deviation from the sinusoidal dependence of the superconducting current on thephase difference between superconducting electrodes is about 20% of the second harmonic. These heterostructuresare found to have sensitivity to an applied magnetic field that is much higher than that of conventionalJosephson junctions. The experimental shape of the magnetic-field dependence of the critical current in the heterostructuresdiffers from the usual Fraunhofer shape by oscillation with a significantly smaller period along amagnetic field.PACS numbers: 74.45.+c, 74.50.+r, 75.70.Cn
