Verwey transition (VT) of Fe3O4 has been extensively investigated as this results in sharp
changes in its physical properties. Exploitation of VT for potential applications in spin/charge …

Superparamagnetic iron oxide nanoparticles (SPIONs,~ 11-nm cores) were PEGylated
without anchoring groups and studied as efficient MRI T 2 contrast agents (CAs). The ether …

We report the phase-composition, structure and magnetic properties of two representative
samples of naturally available iron-oxide containing ores/soils collected from two different …

The spin reorientation temperature T SR of stoichiometric Fe 3 O 4, as well as of magnetite
with a small number of vacancies and magnetite containing a low concentration of Ti, Zn, Al …

To observe, by microscopic probe, how low Zn doping in F e 3− x Z nx O 4 (x is below 1%)
changes the Verwey transition, we have performed Mössbauer spectroscopy measurements …

Submicron-scale magnetite (Fe 3 O 4) hollow spheres were prepared by a template method
using polystyrene beads. The obtained particles were very uniform in size with a diameter of …

Magnetic minerals, such as magnetite and hematite, have been reported to be present, in
particular, leaves as biogenic particles. The magnetic minerals and properties of Ni …

Magnetite is an abundant magnetic mineral that commonly records the ancient magnetic
field in a wide variety of rock types. When cooled below≈ 124 K, magnetite undergoes a …

The magnetic susceptibility (κRT) and saturation magnetization (MS) of microbially
synthesized magnetites were systematically examined. Transition metal (Cr, Mn, Co, Ni and …

Nuclear inelastic-scattering studies were performed to infer temperature evolution of iron
atom dynamics in magnetite samples exhibiting Verwey transition of first-and second-order …
