✦ Synopsis
The types of spin system exhibited by certain Fe-Cr-Ni alloys were studied using the gamma resonance spectra technique. It was evident that the spin systems were significant in determining the magnetic and physical properties of these alloys at low temperatures. It was found that antiferromagnetic and ferromagnetic ordering of the alloys took place in small regions and the character of each region depended upon its Ni content.
