These compounds were synthesized using high-purity rare-earth metals and cobalt. X-ray diffraction patterns taken at room temperature reveal that all compounds have the C15 cubic Laves phase structure. Heat capacity measurements have been performed in the temperature range of 2–300 K without magnetic field and in a magnetic field of 1 and 2 T. The magnetocaloric effect has been estimated in terms of isothermal magnetic entropy change for all solid solutions in magnetic fields up to 2 T. The effect of increasing Er amount in Ho1−x Er x Co2 on the magnetic and magnetocaloric properties will be discussed.application/pdfenghttps://creativecommons.org/licenses/by/3.0/620Magnetic properties of magnetically ordered materials (75.30.-m)Specific heat of magnetic materials (75.40.-s)Magnetoelectric effects (75.85.+t)Article
