| Abstract: | Polycrystalline samples of Ba0.5Sr1.5Zn2(Fe0.96Al0.04)12O22 were synthesized by solid-state reaction method, and structural, magnetic and dielectric properties were investigated. The magnetic data indicate four magnetic spin-order structures exist in the samples. The Curie temperature is found to be 712 K. The sample also exhibits obvious dispersion in dielectric permittivity and dielectric loss values as a function of the frequency at room temperature, which may be interpreted as Maxwell-Wagner type dielectric relaxation. |
