The influence of surfactant addition (SDS 1g, 2g, 3g) on structural, microstructural, magnetic and dielectric properties of Sr2Cu2Fe12O22 hexaferrites, prepared using a coprecipitation method was investigated. XRD analysis show presence of M, Y and α-Fe2O3 phases. SEM micrograph of pure sample shows agglomerated spongy grains; while the SDS-1g sample shows plate like hexagonal structure. TEM confirms the formation of nano-particles. The Ms falls from 45 to 31.47 emu/g, while Hc was found to increase from 75 to 500 Oe but Mr/Ms < 0.5. The dielectric properties show normal behavior with respect to frequency.
