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 La095Ho005InO3, La090Dy005Ho005InO3, La095Ho005In098Sb002O3, La090Dy005Ho005In098Sb002O3 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 Ho3+ ions and Dy3+ - Ho3+ pair of ions were single-phase, but the samples doped with Ho3+ - Sb3+, Dy3+ - Ho3+ - Sb3+ ions contained LaSbO3-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 Dy3+, Ho3+ 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.
