Abstract:
Composite single crystals consisting of nanoscaled Fe3Se4 inclusions encapsulated into the interlayer space of TiSe2 matrix were obtained by the decay of homogeneous Fe0.5TiSe2 intercalation compound. These composites have a high magnetic anisotropy due to the coherent bond between inclusions and the host lattice of TiSe2. The influence of selenium pressure over the composite surface on the composition of the inclusions is studied, and the possibility of controlling their content is demonstrated. The thermodynamic stability of the composite with a small excess of selenium in comparison with the stoichiometric material is established based on theoretical calculations. The estimated energy of the chemical bond between components of the composite is close to the van der Waals bond energy. A method to control the orientation and defects within the inclusions in the host lattice is proposed.

Single-Phase Two-Wire Line:
A single-phase line consists of two solid cylindrical conductors, denoted as x and y. Each conductor carries phasor currents ix and iy, respectively. Given that the sum of these currents is...
Capacitance: Single-Phase And Three-Phase Line
Single-Phase Lines
Consider a single-phase, two-wire transmission line with equal phase spacing energized by a voltage source. One conductor carries a uniform positive charge, while the other carries an equal negative charge. The capacitance C of the line can be derived from the voltage V between the conductors. For a one-meter section of the line, the capacitance is given...
Phase Changes
A substance melts or freezes at a temperature called its melting point and boils or condenses at its boiling point. These temperatures depend on pressure. High pressure favors the denser form of the substance, so typically, high pressure...
Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
