Abstract

Two representatives of Ni(Co)-Mn-Al metamagnetic shape memory alloy system, Ni₄₅Co₅Mn₃₁Al₁₉ and Ni₃₅Co₁₅Mn₃₅Al₁₅, have been studied with respect to their magnetocaloric properties. Experimental study of the magnetocaloric effect by a direct measurement of the adiabatic temperature change ΔT_ad revealed that in both the samples ΔT_ad depends on the measurement protocol as well as on the magnetic prehistory of the samples. For the applied magnetic field μ₀H = 1.93 T, the largest adiabatic temperature change, |ΔT_ad| ≈ 0.7 K, has been observed in the Ni₃₅Co₁₅Mn₃₅Al₁₅ sample at T = 464 K.
