Abstract: Single phase cubic spinel nanocrytalline particles of Al doped Ni_0.2Cd_0.3Fe_2.5O₄ has been synthesised by sol-gel method with an average crystallite size of ∼5 nm. The dielectric constant (ε′) and ac conductivity (σ_ac) shows normal behaviour with frequency. The dielectric properties and ac conductivity in the samples have been explained in the light of Koops phenomenological theory. The impedance analysis shows that grain boundary volume increases with Al doping. ac susceptibility measurements show that the blocking temperature decreases with the Al doping. The variation of blocking temperature in the real and imaginary part of ac susceptibility shows the existence of non-linear phase.
