Samarium–dysprosium–magnesium ferrite materials have been prepared by chemical combustion method. The effect of samarium–dysprosium rare earth ions on loss factor, real and imaginary part of permeability has been studied for Mg[(Sm) 0.6 (Dy) 0.4 ] x Fe 2− x O 4 ( x = 0.01 and x = 0.03) ferrite materials with temperature and frequency by using a Hioki LCR‐Q meter. From thermal variation of loss factor of prepared ferrite materials, it is revealed that ferrite must be used below Curie temperature for low loss factor. The real part of initial permeability initially increases with frequency and for higher frequency its value almost remains constant. The loss factor and an imaginary part of permeability of the ferrite materials decreases with increasing frequency.
