Structural morphology and nonlinear behavior of pure and co-doped Zn1-x-yFexMyO varistors with (M = Cu, Ni)

We report here structural morphology and nonlinear behavior of pure and co-doped Zn 0.90-x Fe 0.1 M x O with (M = Cu, Ni and ( x  = 0.00, 0.10) and (0.00 ≤  y  ≤ 0.20)) at different sintering temperatures ( T s  = 850 and 1000 °C). It is found that the co-doping of ZnO by (Fe + Cu) or (Fe + Ni) up t...
