Abstract

Nanoparticles of Z-type hexaferrites, \({\mathrm {Ba}}_3{\mathrm {Cu}}_2{\mathrm {Al}}_{x/2}{\mathrm {Cr}}_{x/2}{\mathrm {Fe}}_{24 - x}{\mathrm {O}}_{41}\) (x = 0.0, 0.5, 1.0), have been prepared using sol–gel auto combustion method. The XRD patterns for these compositions show the formation of Z-type hexaferrite. The bands near 415–480 and 550–590 cm⁻¹ in FTIR attribute to the bending and stretching of Fe–O bond vibration at octahedral and tetrahedral site of hexaferrite. VSM study shows the highest values of coercivity (911.11 Oe), retentivity (41.5 emu/g), and saturation magnetization (17.5 emu/g) for x = 1. Radiation absorbance investigation in the microwave X-band (8–12.5 GHz) region shows the maximum radiation loss of −31.19 dB (99.99% loss) at frequency 11.14 GHz for x = 0.5 and hence can be used commercially for microwave as well as antenna applications.
