abstract = "In this study, an increase in the reflection loss (RL) value for SrFe(11.9-x)In0.1Snx/2Znx/2O19 samples (x = 0; 0.10; 0.35 and 0.50) is reported. The X-ray diffraction (XRD) pattern of all samples confirmed that the SrFe(11.9-x)In0.1Snx/2Znx/2O19 samples (x = 0, 0.10, 0.35, and 0.50) posses polycrystalline with single phase. We have demonstrated that co-substitution of Zn2+ and Sn4+ ions with a fraction of x = 0.10 reduced the coercivity of the pure nano strontium hexaferrite (SHF) from 346.80 kA/m to 50.34 kA/m. The substitution of Fe3+ ion by Sn2+ and Zn4+ affect the coercivity decreased significantly. Meanwhile, the saturation magnetization and remanence slightly decreases. Hence, the decreasing of coercivity cause the reflection loss (RL) increase from -16.43 dB to -25.62 dB. We believed the RL value can be increased efficiently by reducing the coercivity of the sample obtained by co-substitution of Zn2+ and Sn4+ ions to Fe3+ in the main phase of SrFe11.9In0.1O19.",
