Structural, magnetic and Mössbauer spectral studies of Sm3+ ions doped Mg ferrites synthesized by solid state reaction technique

► The addition of samarium in Mg ferrite has been shown to play a crucial role in modifying the magnetic properties. ► Low value of relative loss factor makes these ferrites useful for inductor and transformer applications. ► The result shows fairly constant values of μi over a wide frequency range, implying the quality of ferrites.
