Abstract
Single crystals of the spinel system NiFe2-x Inx O4 have been prepared with 
and studied by ferrimagnetic resonance techniques in the 
band and in the temperature range 4.2 to 323°K. Magnetic moment variation with indicates that for 
, In3+enter the 
sites but for higher values of 
enter the 
sites. At 0°K, K1 variation with can be explained in terms of single ion energy only if the cubic field splitting parameter aB Fe3+in the site is supposed to increase with In3+. This has been attributed to the contraction of a site due to accommodating a large In3+in the site. The decrease in site Fe3+concentration is seen to increase both |λ 100| and |λ 111| at lower temperatures.
