Effect of annealing on the magnetic ..
2015 6 15 According to Eq. the plot of ΔK 2 versus K 2 C reveals a straight line and the fitting pWith increasing t mill the average crystallite size decreases largely up to 5 h of milling and reduces sluggishly upon subsequent milling. As milled NiO powders t mill ≥30 h exhibit fine nanosized crystallites of around 10.5 nm with significantly large strain as compared to those
