We observed the possibilities of the changing of type of pinning of Abrikosov vorticies from grain-boundary to point type (in the fabricated films) by an increasing of the annealing temperature. It's demonstrated the deposited films contains a superconducting matrix which are the oxigen solid solution in the magnesium diboride crystal lattice like as Mg(B1-уОу)2 , here superconducting critical current density of the films achieves up to 1,8·1011 - 8,2 · 1010А/м2 in the fields 0-1 Т ( if external magnetic field is perpendicular to wafer ) at 20 K. It's demonstrated that for the fabricated heterostructures the IcRn product value is increasing sufficiently as a result of a realization of the resonance-percolation mechanism of charge transport in them.
