Skull melter single crystal growth of magnetite (Fe3O4) - ulvospinel (Fe2TiO4) solid solution members

Magnetoresistance in magnetite: Switching of the magnetic easy axis

“…AC electrical resistance measurements under external magnetic field were performed on PPMS apparatus on magnetite single crystal (triangle-like slice with exposed (1 0 0) type plane; TV = 123.7 K), skull melter grown from 99.99% pure Fe2O3 and annealed for stoichiometry [9].…”

“…22,23 The starting materials were 99.999% purity Fe 2 O 3 and 99.99 purity Al 2 O 3 . Single crystals ͑typically 15 mmϫ5 mmϫ5 mm͒ were isolated from the boules, analyzed for Al and Fe content by the electron microprobe technique, and checked by Laue back scattering, and x-ray powder diffraction.…”

The effect of doping on global lattice properties of magnetite Fe3−xMexO4 (Me=Zn, Ti and Al)

“…The crystals were then subjected to subsolidus annealing under CO/CO 2 gas mixtures to establish the appropriate metal/oxygen ratio [22]. The actual composition and sample uniformity were checked using a microprobe electron [14][15][16] showing the characteristic break, differentiating first and second order Verwey transition.…”
