Abstract :
Single crystals of the spinel system NiFe2-xInxO4have been prepared with 0 < x < 0.47 and studied by ferrimagnetic resonance techniques in the X band and in the temperature range 4.2 to 323°K. Magnetic moment variation with X indicates that for x < 0.25 , In3+enter the A sites but for higher values of x enter the B sites. At 0°K, K1variation with x can be explained in terms of single ion energy only if the cubic field splitting parameter aBFe3+in the B site is supposed to increase with In3+. This has been attributed to the contraction of a B site due to accommodating a large In3+in the A site. The decrease in A site Fe3+concentration is seen to increase both |λ 100| and |λ 111| at lower temperatures.
