MAGNETIC PROPERTIES OF LaInOa WITH PEROVSKITE STRUCTURE DOPED BY Dy<sup>3</sup>+, Ho<sup>3</sup>+, Sb<sup>3</sup>+ IONS
Solid phase synthesis of La<sub>0</sub><sub>95</sub>Ho<sub>0</sub><sub>05</sub>InO<sub>3</sub>, La<sub>0</sub><sub>90</sub>Dy<sub>0</sub><sub>05</sub>Ho<sub>005</sub>InO<sub>3</sub>, La<sub>0</sub><sub>95</sub>Ho<sub>0</sub><sub>05</sub>In<sub>0</sub><sub>98</sub>Sb<sub>002</sub>O<sub>3</sub>, La<sub>0</sub><sub>90</sub>Dy<sub>0</sub><sub>05</sub>Ho<sub>0</sub><sub>05</sub>In<sub>0</sub><sub>98</sub>Sb<sub>002</sub>O<sub>3</sub> ceramic phosphors was carried out. Their crystal structure, magnetization fields dependences at 6 and 300 K and molar magnetic susceptibility temperature dependences were examined. It was established that the samples obtained had a crystalline structure of orthorhombically distorted perovskite. The samples doped with Ho<sup>3</sup>+ ions and Dy<sup>3</sup>+ - Ho<sup>3</sup>+ pair of ions were single-phase, but the samples doped with Ho<sup>3</sup>+ - Sb<sup>3</sup>+, Dy<sup>3</sup>+ - Ho<sup>3</sup>+ - Sb<sup>3</sup>+ ions contained LaSbO<sub>3</sub>-based impurity phase. It was established that in the whole temperature interval of 5-300 K all the investigated samples of indates were paramagnetic. The values of the effective magnetic moments of the Dy<sup>3</sup>+, Ho<sup>3</sup>+ paramagnetic ions were slightly less than the theoretical values of the spin-orbital magnetic moments of these ions. It was shown that at 300 K increasing of the magnetic field up to 10 T leads to a linear increase in paramagnetic specific magnetization of all indates investigated. At temperature of 6 K magnetization of all the samples studied with increasing magnetic field up to 10 T increases non-linearly with a gradual approach to magnetic saturation, but at 10 T it is not achieved.
