The degree of alignment and its influence on the coercive force in SrFe12O19 crystallites consolidated by SPS.

Goethite and hematite with targeted morphologies dry mixed and cold-pressed with SrCO3, with subsequent sintering to achieve highly aligned hexaferrite. Goethite needles offered the best alignment both magnetically and crystallographically.

In situ neutron powder diffraction (NPD) was employed for investigating gram-scale reduction of hard magnetic CoFe2O4 (spinel) nanoparticles into CoFe2O4/CoFe2 exchange-spring nanocomposites via H2 partial reduction.
