英文摘要	To enhance the magnetocaloric effect of the second-order magnetic phase transition is eagerly sought in the development of practical magnetic refrigeration technology. Here, demonstrated by Dy2In1-xAlx (0 <= x <= 0.5) system, the max magnetic entropy change is significantly enhanced to 13.4 Jkg(-1) K-1 in Dy2In0.7Al0.3 and 10.8 Jkg(-1) in (DyIn0.6)-In-2,Al-0.4 alloys compared with 8.8 Jkg(-1) K-1 in Dy2In through a field-induced metamagnetic phase transition, which is unconventionally of nonhysteresis confirmed by magnetic measurements. Considering that nonhysteresis metamagnetic transition occurs at the critical composition where hexagonal structure is formed for x <= 0.3 while orthorhombic structure for x >= 0.4, the origin is ascribed to the lattice distortion.
