The paper reports on the ferromagnetic resonance (FMR) and magnetometry studies of the epitaxial superconductor/ferromagnet-type thin film heterostructure of VN/Pd0.96Fe0.04 on the (001)-oriented MgO substrate. Vanadium nitride layer was deposited by dc reactive magnetron sputtering of the V-target in the mixture of the Ar and N2-gases. Pd-Fe layer was grown by molecular beam deposition in the ultrahigh vacuum conditions. LEED patterns and XRD analysis revealed the "cube-on-cube" epitaxy at both the MgO/VN and VN/Pd0.96Fe0.04 interfaces and single crystalline structure of both layers. Ferromagnetic resonance spectra revealed a single absorption line with strong orientation dependence and manifestations of superconductivity of the VN-layer at a temperature of 4.2 K. Magnetic anisotropy constants for the Pd0.96Fe0.04 layer were found from the analysis of the orientation dependence of the FMR resonance field and were compared with that of the film of the same composition grown directly on MgO. We find that the tetragonal distortion for Pd0.96Fe0.04 on the VN layer is reduced due to a relaxed lattice mismatch with respect to MgO.
