[en] A large change in the magnetic entropy, |ΔS|, was observed in the Fe-based NaZn₁₃-type compound LaFe_11.375Al_1.625, which was nearly temperature independent over a wide temperature range (an about 70 K span from ∼ 140 to 210 K). This behaviour of the magnetic entropy change is associated with two closely spaced magnetic transitions. X-ray diffraction investigation at different temperatures indicates that the crystal structure remains cubic, of NaZn₁₃ type, when the magnetic state changes with temperature, but the cell parameter changes dramatically at the first-order transition point
