Nickel‐doped cobalt nanoferrites (Ni x Co 1‐x Fe 2 O 4 , where = 0.0 to 1.0 with step size 0.2) were prepared using the auto combustion method in which aloe vera extract was taken as a fuel. Further, characterization for antimicrobial, structural, optical, and magnetic studies performed ferrite nanoparticles. Antimicrobial activity assessed against prevalent human fungal pathogen, Candida albicans . The X‐ray diffraction (XRD) pattern confirmed spinel cubic phase an average crystallite of 28 nm. Fourier transform infrared spectroscopy (FTIR) stretching mode vibration at tetrahedral octahedral sites. analysis properties done vibrating sample magnetometer (VSM), parameters, specific magnetization (67.69 emu/g) well squareness ratio σ R / S (0.47) observed. From UV–Visible absorbance spectra, band edge observed between 700 800 nm, gap values 2.84 eV 1.0. Furthermore, antimicrobial obtained nanoparticles inspected C. fungi, it that nickel‐doped shows inhibitory nature. Maximum inhibition 0.43 (67% growth) composition Therefore, these can be used drug fungus infection.
