Аннотация: Using our data on magnetic entropy change О” S m, adiabatic temperature change О” T a d and heat capacity CH for La(FeCoSi)13 alloys, the upper limit of heat Qc transferred per cycle, and the lowest limit of consumed work Wc were established for magnetic refrigerators operating in О” Ој 0 H 1.9 T. In order to estimate the cooling power, attributable to thermoelectric refrigerators with La(FeCoSi)13, thermal conductivity О», resistivity ПЃ, and Seebeck coefficient О± were measured and the maximal cooling power QL, the input power Pi, and coefficient of performance have been calculated.
