Cationic Ordering, Solid Solution Domain, and Diffuse Reflectance in Fe2WO6 Polymorphs
The Journal of Physical Chemistry C
Single phases of the α, β, and γ polymorphs of the Fe2WO6 iron tungsten oxide were obtained through an aqueous solution route based on the combustion and heat treatment of a spray-dried precursor powder. Syntheses with Fe/W ratios ≠ 2 identified a domain of solid solutions consistent with a Fe2–2xW1+x□xO6 scenario (x up to ∼0.025) for the defect chemistry in the temperature range around 850 °C. The crystallographic characterizations revealed a random cationic distribution in an α-PbO2-type cell…
Single phases of the α, β, and γ polymorphs of the Fe2WO6 iron tungsten oxide were obtained through an aqueous solution route based on the combustion and heat treatment of a spray-dried precursor powder. Syntheses with Fe/W ratios ≠ 2 identified a domain of solid solutions consistent with a Fe2–2xW1+x□xO6 scenario (x up to ∼0.025) for the defect chemistry in the temperature range around 850 °C. The crystallographic characterizations revealed a random cationic distribution in an α-PbO2-type cell for the low-temperature polymorph (α) and pointed to a reconstructive mechanism for the formation of polymorph β. A comparison of diffuse reflectance spectra confirmed the visual observation of minor color differences between the polymorphs by revealing small shifts of the absorption threshold; the Kubelka–Munk function and Tauc plots were used for comparison of the polymorphs and discussion of the results with respect to relevant literature.

Original Network of Zigzag Chains in the β Polymorph of Fe2WO6: Crystal Structure and Magnetic Ordering
Inorganic Chemistry, American Chemical Society
The structural and physical properties of the β polymorph of iron tungstate Fe2WO6 have been investigated by synchrotron and neutron diffraction vs temperature, combined with magnetization and dielectric properties measurements. The monoclinic P21/a crystal structure of β-Fe2WO6 has been determined and consists of an original network of zigzag chains of FeO6 and WO6 octahedra sharing trans and skew edges, connected through corners into a 3D structure. Magnetization measurements indicate an…
The structural and physical properties of the β polymorph of iron tungstate Fe2WO6 have been investigated by synchrotron and neutron diffraction vs temperature, combined with magnetization and dielectric properties measurements. The monoclinic P21/a crystal structure of β-Fe2WO6 has been determined and consists of an original network of zigzag chains of FeO6 and WO6 octahedra sharing trans and skew edges, connected through corners into a 3D structure. Magnetization measurements indicate an antiferromagnetic transition at TN = 264 K, which corresponds to a ↑↑↓↓ nearly collinear ordering of iron moments inside sequences of four edge-sharing FeO6 octahedra, as determined by neutron diffraction. A canting of the moments out of the ac plane is observed below 150 K, leading to a noncollinear antiferromagnetic structure, the P21/a′ magnetic space group remaining unchanged. These results are discussed in comparison with the crystal and magnetic structures of γ-Fe2WO6 and with the magnetic couplings in other iron tungstates and trirutile Fe2TeO6.

Statistical Thermodynamics
Score: 13/20 (65%)
The objective of the course is to provide fundamental knowledge of statistical mechanics. One important goal is to give a deep understanding of the concept entropy and to overcome the discrepancy between a microscopic (statistical mechanics) and a macroscopic approach (thermodynamics). Another important goal is to obtain an understanding of the importance of intermolecular interactions on different properties.

One important goal is to give a deep understanding of the concept entropy and to overcome the discrepancy between a microscopic (statistical mechanics) and a macroscopic approach (thermodynamics). Another important goal is to obtain an understanding of the importance of intermolecular interactions on different properties.
Course contents
Lectures: To start with, a fundamental concept of statistical mechanics is introduced. Transformations in thermodynamics are related to the corresponding ensembles in statistical mechanics. Effort is typically made to relate thermodynamics and statistical mechanics. After that, properties of systems with non-interacting particles are studied. Then we consider systems consisting of interacting particles, and, for example, an exact expression for the second virial coefficient is derived.
Project: A project is carried out, where statistical mechanical theory is applied on problems related to ongoing research (computer simulations).
