This scientific report shows that such objects are alloys of molybdenum with rhenium with different concentrations of constituent elements. By means of quantum point spectroscopy, direct evidence of the presence of two energy slits in these alloys was obtained even at equal concentrations of molybdenum and rhenium. It is shown that the studied alloys of molybdenum with rhenium can be used to implement new quantum effects associated with the phase difference of electronic wave functions in different zones. A new superconducting quantum device based on multilayer heterostructures with Josephson transport and a weak bond very sensitive to magnetic fields has been proposed and implemented. It is a periodic structure of ferromagnetic and normal metal nanoscale layers that are close to superconducting niobium electrodes. The theoretical analysis proposed in the work shows that the field sensitivity of such a device, which is a promising candidate for the role of magnetic field nanosensors of the new generation, is twice the sensitivity of modern micro- and nano-SQUIDS.
