Abstract
The microwave and magnetic parameters of Josephson Nb/Au/Sr2IrO4/YBa2Cu3Ox mesastructures with a layer of Sr2IrO4, a material representing a Mott antiferromagnetic insulator with a high spin–orbit interaction energy ESO ~ 0.4 eV, were studied. Shapiro steps, oscillating with radiation power, appeared under monochromatic electromagnetic radiation confirm the Josephson properties of these structures. In the presence of a weak magnetic field H < 15 Oe, the voltage–current characteristics (VCCs) had resonant current steps at voltages Vn, which were inversely proportional to the size L of structures in plane. Polarity reversal in the electrical current I led to asymmetry in the arrangement of resonant current steps. At a specified magnetic field H, the voltage Vn remained constant, and the amplitudes of resonant current steps nonmonotonically changed.
