| Description
| - A number of samples extracted from the human brain (basal ganglia) have been investigated by the scanning and transmission electron microscopy (SEM/TEM), SQUID magnetometry, and Mössbauer spectroscopy at ambient and cryogenic temperatures. A considerable amount of biomineralized iron-oxides was found in the extracellular matter. This material refers to perfect single crystals of the size 50 - 1000 nm and the TEM mode, after indexing, allows their identification as magnetite Fe3O4 and/or hematite ?- Fe2O3. The SQUID magnetometry reveals a classification of the samples into three groups: dominating diamagnetism (I), dominating paramagnetism (III), and the intermediate class (II). The magnetic response reflects an overall distribution of nanoparticles of different size and surface/bulk ratio. In class III the bifurcation point of the zero-field-cooled-magnetization and field-cooled-magnetization curves lies above the multicomponent contributions. The registered response is completely different from that measured for the ferritin - an iron storage protein where the ferrihydrite core of 6 nm in size exhibits superparamagnetism with the blocking temperature Tb = 11 K and the critical temperature Tc = 20 K. room temperature and consequently the magnetic hysteresis has been identified even at the room temperature. The shape of the hysteresis loop is complex, owing to the
