“…The orbital-ordered ferromagnetic state of 3 is easily destroyed, which causes ferromagnetism, but this ferromagnetic behavior can take place by means of several mechanisms, depending on the cation and level substitution. The physical properties can be derived from a complex interaction between the exchange interactions, the orbital-ordered state, and Jahn-Teller distortion (JT) [5][6][7][8][9][10][11][12][13].…”

This paper presents the results obtained from the synthesis and morphological characterization of different magnetite samples: La0.67-x Prx Ca0.33 MnO3.LaMn1-x Cox O3 and LaMn1-x Nix O3 at 0.13 ≤ 𝑥𝑥 ≤ 0.67 produced by a solid-state reaction mechanism and 𝐿𝐿𝐿𝐿𝑀𝑀𝑀𝑀1−𝑥𝑥(𝐶𝐶𝐶𝐶/𝑁𝑁𝑁𝑁)𝑥𝑥𝑂𝑂3 at 0.0 ≤ 𝑥𝑥 ≤ 0.5 produced by the sol-gel method. These samples were characterized using X-ray diffraction spectroscopy and by measuring electric resistivity and magnetic susceptibility which were carried out as a function of temperature. Notably, the effects of strain and compressive strength on the lattices of magnetite samples were highly dependent on the concentration of 𝑃𝑃𝑟𝑟, 𝐶𝐶𝐶𝐶, and 𝑁𝑁𝑁𝑁. Moreover, the transition temperatures of metal-insulator and ferromagnetic-paramagnetic phases also largely depend on these strength effects, e.g., at higher concentrations of 𝑃𝑃𝑟𝑟, effects of increased strain strength were observed, relocating the shifts of ferromagnetic-paramagnetic transitions to lower temperatures. On the other hand, effects of increased compressive strength were observed at higher concentrations of 𝑁𝑁𝑁𝑁 and 𝐶𝐶𝐶𝐶, relocating the shifts of ferromagnetic-paramagnetic and metal-insulator transitions to higher temperatures.

Within the framework of linear response theory, an exact expression for the energy dissipation of irradiation in disordered condensed matter is derived. There it is made use of Kubo's formalism for the treatment of a mechanical disturbance. This approach delivers a generalization of the known fluctuation‐dissipation theorem, a novel relationship between the time autocorrelation functions of the quantities M and dM/dt (M: dipole moment operator), and an explanation of the anomalous temperature dependence of the far infrared absorption band shape, e. g. of dilute solution of acetonitrile. Several limiting cases are discussed, e.g. vanishing density.
