摘要：

In the present study, we have synthesized tri-substituted strontium hexaferrites SrFe Cu(12-2x) Co-x/2 Zr-x/2 (x) O (19) (x= 0.0 -1.0, Delta x= 0.2) by sol-gel auto-combustion route. The effect of this triple doping has been studied on the structural, dielectric, and magnetic properties of M-type strontium hexaferrite nanoparticles. The characterization of these materials has been done by XRD, FT-IR, VSM, SEM, EDS, and impedance analyzer. Single-phase formation is confirmed at 800 C-ay. Real permittivity decreases while loss tangent increases with increase in substitution. The observed results propose these prepared ferrites for applications in filters, antennas, isolator, circulators, etc.
