Magnetic Barium Hexaferrite Nanoparticles with Tunable Coercivity as Potential Magnetic Heating Agents.

Influence of the Duration of Calcination d cal Changing the duration of calcination (d cal ) ( Figure 1 ) does not result in a clear trend in the crystallite size of the particles, as determined by XRD.

For crystallinity ( Figure 3 b), a slightly increasing trend can be assumed, with higher T cal leading to higher crystallinities.
