“…At a temperature of 140 K, the resistivity of the sample increased from 5 Ω (x=0) to 340 Ω (x=0.10) upon systematic doping. The Cu substitution on the Mn position can change the value of resistivity, lattice parameters, and the transition temperature [11][12][13][14]. The effect of Cu substitution on the Mn position can change the order of the orbital Mn 3 + ions, as well as weaken the double-bond exchange between Mn 3 + and Mn 4 + .…”

The study of the perovskite manganites La0.47Ca0.53Mn1-xCuxO3 with x = 0, 0.06, 0.09, and 0.13 has been done. The magnetic structure was determined using high-resolution neutron scattering at room temperature and low temperature. All samples were paramagnetic at room temperature and antiferromagnetic at low temperature. Using the SQUID Quantum Design, the samples showed that the doping of the insulating antiferromagnetic phase La0.47Ca0.53MnO3 with Cu doping resulted in the temperature transition from an insulator to metal state, and an antiferromagnetic to paramagnetic phase. The temperature transition from an insulator to metal state ranged from 23 to 100 K and from 200 to 230 K for the transition from an antiferromagnetic to paramagnetic phase.

“…It was shown in a number of works that simultaneously with doping of LaMnO 3 with alkaline-earth elements within the perovskite structure, Mn may be replaced by other 3d metals-Fe, Cu, Cr and Co [2][3][4][5][6][7][8][9][10][11]. Such double substitutions usually lead to appreciable changes in the structure and physicochemical properties, and therefore it becomes possible to create materials for new functional purposes on the basis of these substances.…”

“…The ferromagnetic state is possibly caused by the double exchange between manganese and chromium ions, which have almost the same electron configuration as Mn 4+ ions [24,25]. In manganites doped with chromium, a decrease in Curie temperature, increase resistivity and decrease temperature of transition from metal to semiconductor can be observed with increase in chromium concentration [26][27][28][29][30][31].…”

Nanocrystalline La0.9A0.1Mn0.9Cr0.1O3 (A: Li, K, Na) powders have been synthesized by combustion method. The powders were used to prepare ceramics by high-pressure low-temperature sintering technique. For all samples the structure, elemental composition and morphology were studied using X-ray diffraction (XRD), Raman spectroscopy, Energy-Dispersive X-ray Spectroscopy (EDS) and Scanning electron microscopy (SEM). Magnetic properties were studied using magnetometry methods and the valency changes of the cations after alkali ions doping were studied using X-ray photoelectron spectroscopy (XPS). The influence of the sintering pressure on the structural and magnetic properties of the manganites doped with different alkali ions and chromium was also investigated. Magnetization properties were studied as a function of sintering pressure and type of the dopant. Chemical doping with alkali ions as well as external pressure significantly changed the magnetic properties of the compounds. It was found that the magnetic properties of the manganites could be predictably modified through the use of a suitable dopant element.
