Abstract: Disclosed is a thermomagnetic generator which converts thermal energy to electrical energy without intermediate conversion to mechanical work, and comprises a series of at least three different metal-based thermomagnetic materials whose magnetocaloric effect occurs at different temperatures, such that the conversion of thermal energy to electrical energy can exploit an enlarged temperature range. The compounds suitable for the invention are selected from: (1) (AyBy-1)2+äCwDxEz Where A is Mn or Co, B is Fe, Cr or Ni, C, D and E at least two of C, D and E are different, have a non-vanishing concentration and are selected from P, B, Se, Ge, Ga, Si, Sn, N, As and Sb, where at least one of C, D and E is Ge or Si, (2) La(FexAl1-x)13Hy or La(FexSi1-x)13Hy (II) La(FexAlyCoz)13 or La(FexSiyCoz)13 (III) LaMnxFe2-xGe (IV) 4) Gd5(SixGe1-x)4 (V) (5) Fe2P-based compounds, (6) manganites of the perovskite type, (7) Tb5(Si4-xGex) (VI) or XTiGe (VII) where X = Dy, Ho, Tm, (8) Mn2-xZxSb (VIII) or Mn2ZxSb1-x (IX)
