Structural And Magnetic Study Of Nickel Doped Nanocrystalline Z Hexaferrite With Increase In Temperature<br>
<br>

<strong>Abstract</strong><br>
The synthesis of nanocrystalline Z-type 
Hexaferrite Sr3Ni2Fe24O41  powders by conventional 
ceramic method at two different temperature 600°C 
and 800°C has been investigated and consequently, 
low temperature sintering and good magnetic 
properties were achieved. The phase identification of 
the sample was carried out by XRD.  The 
microstructure of the sintered sample was studied by 
SEM indicates that the ferrite formed are hexagonal 
shape having crystalline size in the range of 90nm to 
100nm. Magnetic properties were discussed by M-H 
curve using Hysteresis loop tracer and it is found that 
with increasing in sintering temperature coercivity as 
well as retentivity of Hexaferrite increases whereas 
saturation magnetization remains same.
