The effects of substitutional and interstitial atoms on the magnetic and magnetocaloric properties are investigated for RNi (R is rare earth) compounds attractive for magnetic solid-state cooling at cryogenic temperatures. We focused on combining weakly and highly anisotropic rare earth compounds and obtained GdxDy1-xNi (x = 0.1 and 0.9) compounds and their GdxDy1-xNiH3 hydrides. The magnetocaloric effect values of GdxDy1-xNiHy (y = 0 and 3) in the vicinity of Curie temperatures were obtained and compared with literature data for the final GdNi and DyNi compounds. The observed effects were explained based on altered exchange and magnetocrystalline interactions in the modified compounds.
