Magnetic properties and metastable states of Co-Ir films
The phase composition, crystal structure, and magnetic properties of Co1 − xIrx alloy films with x = 0.35–0.8 and fabricated by chemical deposition are studied. Saturation magnetization vs. composition and temperature, coercivity, and magnetization reversal of the films are investigated experimentally. It is shown that in the region of equiatomic composition, Co-Ir films have a two-phase hexagonal close-packed structure that alternates with disordered regions, producing halos in electron diffraction patterns.
