Abstract

Objective: The nickel ferrite is promising magnetic material and has several applications; ranging from radio frequency and microwave frequency. They can used in transformers, inductors, antenna rods, memory chip etc. Recently they have find applications in sensors green anode materials and drug delivery.


Materials and Methods: A nominal composition of NiCrxFe2-2x with x varying (0.0, 0.1, 0.2, 0.3, 0.4, 0.5 and 0.6) has been prepared by Sol-Gel auto-combustion method.


Chemicals such as nickel nitrate hexahydrate, Chromium nitrate nonahydrate, ferric nitrate nonahydrate and Dextrose used as fuel. Ammonia Solution was added to maintain pH 7. synthesis powder is sintered at 750 0C for 6 hours.


Results: XRD for all sample recorded at room temperature model (3710) using Cu-K radiation (=1.5406 Å). Infrared (IR) spectra were recorded using Fourier transform infrared spectrometer (Perking Elmer Instruments USA) in range 1000-370cm-1 with resolution 1 cm-1. Magnetic properties of nanoparticles were performs using pulse field hysteresis loop, XRD pattern shows broad peaks. IR spectra confirmed spinel cubic structure, saturation magnetization, remanence magnetization, coercivity decreases with increase in chromium substation.


Conclusion: Using sol-gel method the particle size of about 15-33 nm was achieved. The obtained values of coercivity revealed that the prepared samples possess nano-crystalline nature.

Keywords: Nickel ferrite, sol gel method, Magnetic properties, XRD
