In Dy 2 In 1-x Al x (x = 0, 0.2, 0.3 and 0.4) alloys, the hexagonal structure is gradually transformed into orthorhombic one with x = 0.3 as the critical composition. In Dy 2 In 0.7 Al 0.3 alloy, the highest magnetic entropy change is accompanied with highest saturation magnetostriction ∼995 ppm under 7 T near phase transition temperature, indicating the typical strong magnetoelastic coupling. From heat-capacity ( C p ) measurement, a sharp peak is observed on the C p - T curves for Dy 2 In 1-x Al x (x = 0, 0.2 and 0.3) alloys. Meanwhile, more Al substitution for In leads into the reduced density of state near Fermi level of each alloy judged from C p /T - T 2 curves. The maximized ΔT ad for a field of 7 T is slightly increased from 6.5 K in Dy 2 In to 7 K in Dy 2 In 0.7 Al 0.3 .
