Comparative study of iron-containing haematinics from the point of view of their magnetic properties

The dynamic magnetic susceptibility of several haematinics in which iron is present as antiferromagnetic salts or iron oxyhydroxide nanoparticles has been measured. Among other parameters, the temperature dependence of the AC susceptibility of each compound acts as a fingerprint that informs about microstructural aspects of the presence of iron. The physicochemical characterisation of these compounds is of great relevance with respect to their bioavailability in the treatment of iron deficiency anaemia.
