TL;DR: Several iron oxides and mixtures have been prepared by heating the product of a sol-gel reaction between iron(III) nitrate and ethylene glycol in different atmospheres and at different temperatures as mentioned in this paper.

TL;DR: In this paper, the authors show detailed magnetic absorption spectroscopy results of an in situ cleaved high-quality single crystal of magnetite and optimize the experimental setup to reduce drift, self-absorption, and offset phenomena as far as possible.
Abstract: We show detailed magnetic absorption spectroscopy results of an in situ cleaved high-quality single crystal of magnetite. In addition the experimental setup was carefully optimized to reduce drift, self-absorption, and offset phenomena as far as possible. In strong contradiction to recently published data, our observed orbital moments are nearly vanishing and the spin moments are quite close to the integer values proposed by theory. This very important issue supports the half-metallic full-spin-polarized picture of magnetite.

TL;DR: In this article, a large, single crystals of magnetite, 1 cm in diameter and up to 4.3 cm long, of high purity and perfection have been grown from the melt.
Abstract: Large, single crystals of magnetite, 1 cm in diameter and up to 4.3 cm long, of high purity and perfection have been grown from the melt. The density at 20° is 5.185, i.e., 99.58 percent of the x‐ray density. The composition corresponds to stoichiometric Fe3O4 within analytical error. Phase diagram considerations, growing procedure, methods of chemical analysis, and composition data are discussed.

TL;DR: In this paper, magnetite nanoparticles were applied to remove Cu (II) from aqueous solutions, and the adsorption process was found to be pH-dependent.
