Could Nd substitution in hexaferrites increase their magnetocrystalline anisotropy and, correspondingly, thier coercivity?

In hexaferrites, a Ba2+ or Sr2+ ion substitutes an oxygen ion (O2-) in some of the hexagonal close-packed oxygen layers; this is possible seemingly due to the similarity of the ionic radii (1.35 A...

How can a magnetic hysteresis loop characteristic of a single ferromagnetic phase explain the magnetic behavior of a multiphase system?

M-type barium hexaferrite is known to be a hard magnetic material with a typical coercivity of few thousand Oe. Upon substitution of Fe ions by certain metallic ions and sintering at high enough...

Has anyone come across a reference concerning the fabrication and structural characteristics of barium ferrite (Ba3Fe2O6) phase?

In the course of preparing barium ferrites this peculiar phase showed up under certain conditions. What is the space group and properties of this phase? Is there any reference?
