Biomineralization of Fe3O4 in Bacteria

1984
Iron is a constituent of the active sites of many important proteins including hemoglobin and myoglobin, the cytochromes, iron-sulfur proteins, nitrogenase and others. Because of the importance of the iron-containing proteins to the physiology of a wide variety of organisms, their physical and electronic structures have been extensively studied.

Dielectric relaxation in Fe3O4

physica status solidi (a), 1985
Dielectric relaxations arising from the Maxwell-Wagner interfacial polarization and intrinsic electron hopping are found for Fe3O4 at the temperatures of 113 and 37 K. The distribution of the layers in the heterogeneous structure is obtained for the distribution of relaxation times in dielectric relaxation due to the Maxwell-Wagner interfacial ...

2011
Solid solutions with spinel structure in the Fe3O4???Mn3O4???Co3O4 system were synthezed in the air. If Co3O4 exceeds 50 % mol. solutions split into 2 spinel phases. Parameters of elementary gate, magnetic moment and Kuri point were studied. It was found that relation enthalpy in forming spinel compounds and solid solutions to the total sum of enthalpy
