An experimental study has been done on amorphous Fe₇₈Gd₂B₂₀ (S1), Fe₇₆Gd₄B₂₀ (S2), and Fe₇₄Gd₆B₂₀ (S3) alloys to understand their electrical, phase transformation, and magnetic properties. Four Probe Technique (FPT), Differential Scanning Calorimetry (DSC), X-Ray Diffraction (XRD), and Vibration Sample Magnetometer (VSM) were used to characterize the samples. Resistance versus temperature curve of the fresh sample Fe₇₈Gd₂B₂₀ (S1) showed a sudden drop around 800 K, indicating the amorphous for crystalline transformation of the sample. The resistivity of samples S1, S2, and S3 at room temperature was found to be 273.3 µΩ-cm, 242.1 µΩ-cm and 147 µΩ-cm, respectively. Temperature Coefficient of Resistance (TCR) of the samples S1, S2 and S3 was found to be 1.38 x 10^-4 K^-1,1.40 x 10^-4 K^-1 and 2.60 x10^-4 K^-1, respectively. The phase transformation and structural studies have been done using Differential Scanning Calorimetry (DSC) in the temperature range of 30 ⁰C – 1000 ⁰C. The DSC curve of sample S1 showed an exothermic sharp peak around 555 ⁰C (828 K), indicating the amorphous to crystalline transformation. Thus, sample S1 showed single step crystallization. Samples S2, and S3 showed multi step (growth of different phases) crystallization. XRD studies showed the presence of α-Fe phase in the crystallized S1 sample. From VSM studies, the coercive field (H ) of the samples S1, S2, and S3 was found to be 0.00 O_e', 0.10 O_e', 1.69 O_e and the saturation magnetization (M ) was found to be 4.911 emu, 0.897 emu, 0.679 emu, respectively.
