Magnetic properties and metastable states of Co-Ir films / E. M. Artemiev [et al.] // Bull. Russ. Acad. Sci. Phys. - 2014. - Vol. 78, Is. 2. - P. 134-135, DOI 10.3103/S1062873814020063. - Cited References: 3 . - ISSN 1062-8738

Аннотация: The phase composition, crystal structure, and magnetic properties of Co1 - x Ir x 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.

Аннотация: The interaction between a solid inert metal (Ir) and an active liquid metal (Ga) during mechanical activation in a high-energy planetary mill is studied by X-ray diffraction and scanning electron microscopy with EDS-apparatus for high-resolution energy dispersive X-ray microanalysis. The influence of mechanical activation conditions on the formation of GaxIry intermetallic compounds and GaxIry/Ir composites and on their solubility in various acids is investigated. Being a surfactant for iridium, gallium propagates along the grain boundaries of polycrystalline iridium particles during mechanical activaiton and, hence, sharply decreases their strength. As a result of strong mechanical deformation during activation, the contact surface area between the solid and liquid metals, where the intermetallic compounds form intensely, increases sharply. As a result of treatment of the products of mechanical activaiton by a mixture of concentrated hydrochloric and nitric acids, iridium (>30%) from passes into an acid solution and forms HxIrCly complex compounds, which can interact with bases to form soluble complex salts.
