• Abstract Single-layer vanadium nitride (VN) and bilayer Pd0.96Fe0.04/VN and VN/Pd0.92Fe0.08 thin-film heterostructures for possible spintronics applications were synthesized on (001)-oriented single-crystalline magnesium oxide (MgO) substrates utilizing a four-chamber ultrahigh vacuum deposition and

• ; epitaxial superconductor–ferromagnet heterostructure; palladium–iron alloy (PdFe); vanadium nitride (VN); superconducting spintronics; Introduction Since its invention, rapid single-flux quantum (RSFQ) logic [1][2] based on superconducting digital electronics has been seriously considered as an alternative

• choice for superconducting MRAM materials, in which vanadium nitride (VN) serves as the superconductor. The magnetic anisotropies of a 20 nm thick Pd0.96Fe0.04 film of the first-generation epitaxial sample of VN/Pd0.96Fe0.04 on MgO(001) were studied by using a ferromagnetic resonance technique in [34
