Image of FIG. 1.
FIG. 1.

The XRD pattern for the In-15 and In-15.5 samples.

Image of FIG. 2.
FIG. 2.

(a) The temperature dependence of electrical resistivity of the In-15 sample in zero and 80 kOe magnetic fields. The inset shows the temperature regime where the electrical resistivity exhibits a thermal hysteresis. Magnetic field does not have any effect on the electrical resistivity in this temperature regime. (b) The temperature dependence of MR of the In-15 sample for 80 kOe applied magnetic field.

Image of FIG. 3.
FIG. 3.

(a) The temperature dependence of low field magnetization of the In-15 sample. The inset shows the temperature dependence of the inverse of magnetic susceptibility obtained from this low field (100 Oe) magnetization curve. The fitted straight line represents the Curie–Weiss law. (b) Isothermal field dependence of magnetization of the In-15 alloy. (c) Arrott plots obtained from the isothermal field dependence of magnetization. (d) The temperature dependence of spontaneous magnetization of In-15.

Image of FIG. 4.
FIG. 4.

Isothermal field dependence of magnetization of the In-15 sample at 5 K. The virgin magnetization curve is drawn while increasing field from 0 to 80 kOe, starting from the zero field cooled state. The envelope magnetization curves are drawn subsequently, while cycling the field between 80 and −80 kOe.

Image of FIG. 5.
FIG. 5.

(a) MHLs drawn on the isothermal field dependence of magnetization of the In-15 sample at 5 K. Each MHL was drawn starting from the zero field cooled state. (b) Isothermal field dependence of magnetization of the In-15 sample at 5 K drawn after cooling the sample from 300 K in the presence of 50 kOe applied magnetic field.

Image of FIG. 6.
FIG. 6.

(a) The temperature dependence of electrical resistivity of the In-15.5 sample in zero (open symbols) and 80 kOe (closed symbols) magnetic fields. The inset shows this curve between 200 and 375 K for zero magnetic field. The signature of the Curie temperature is clearly seen on this inset. (b) The temperature dependence of MR of the In-15 sample for 80 kOe applied magnetic field. The inset shows the isothermal field dependence of electrical resistivity of the alloy.

Image of FIG. 7.
FIG. 7.

(a) The temperature dependence of low field (100 Oe) magnetization of the In-15.5 sample. The inset shows the temperature dependence of the inverse of magnetic susceptibility obtained from this low field magnetization curve. The fitted straight line represents the Curie–Weiss law. (b) Isothermal field dependence of magnetization of the In-15.5 alloy when it is well inside the martensite phase. (c) Isothermal field dependence of magnetization of the In-15.5 alloy showing the field induced martensite–austenite phase transition. (d) Isothermal field dependence of magnetization of the In-15.5 alloy inside the austenite phase.

Image of FIG. 8.
FIG. 8.

(a) The temperature dependence of heat capacity of the In-15 and the In-15.5 alloys. The inset shows that magnetic fields up to 50 kOe does not have any effect on the austenite–martensite phase transition of the In-15 alloy. (b) The temperature dependence of entropy of the In-15 and the In-15.5 alloys. The inset shows the field dependence of heat capacity of the In-15 alloy at 5 K.
