Abstract
Electron paramagnetic resonance in YAG:Nd3+ crystals grown by the hori zontally directed crystallization method is investigated in 8 mm range . The upper boundary for Nd3+ ions concentration in octahedric positio ns of YAG:Nd3+ crystals has been found not to exceed 5-7 % of the tota l neodymium concentration in dodecahedric positions of the lattice. Fo r the first time the temperature dependence of the magnetic susceptibi lity of YAG:Nd3+ crystals grown by the method has been experimentally investigated in 5-300 K range. A good agreement between the experiment and the theory, assuming that all neodymium ions are only in c-positi ons of the lattice, has been found. Neodymium ions concentration in th e tested crystals has been determined, and the diamagnetic contributio n to the magnetic susceptibility has been estimated.
