In this report a review of magnetic properties of two groups of intermetallic compounds in relation with their magnetocaloric effect properties is presented. A first group of materials concerns the MM’X type (M, M’-metal 3d or 4d, X = As, P, Ge) of compounds. In this group the MnRh1-xCoxAs and MnFe1-xCoxP series of solid solutions are investigated. In a second group of materials, the Mn1-xTxAs (T = Cr, V, Ti, (Ti0.5V0.5) ) series of compounds are analyzed. In this case a special attention is paid for high dc field magnetization measurements and for selected compounds. As a summary the magnetic entropy change vs. M, M’ or T transition metal concentration for F-P phase transitions will be shown. Furthermore results of KKR-CPA electronic band structure computations in relation to magnetic properties are discussed.
