A nickel–indium (Ni–In) ferromagnetic alloy is successfully synthesized through a facile pulsed electrodeposition method. The composition, structure, and morphology are analyzed through atomic absorption spectroscopy (AAS), X‐ray diffraction (XRD), X‐ray photoelectron spectroscopy (XPS), and electron microscopy. The composition and structural analysis indicate fcc phase for the Ni 43 In 57 and Ni 63 In 37 alloys. The Ni–In alloy shows mixed phases when the Ni content is increased from 63 to 66 at%. Thermal analysis of the Ni 63 In 37 results in an activation energy of 46 and 557 kJ mol −1 that can arise from the grain growth phenomena and phase transformation, respectively. Thermomagnetic studies show a Curie temperature of 340 °C for the Ni–In alloy with 63 at% Ni that also exhibits a saturation magnetization of 36 emu g −1 .
