- Abstract
Studies of dodecaboride LuB12 in the temperature range of 10–300 K show that the 175Lu spectrum is broadened due to the scatter of quadrupole frequency shifts caused by the defects in the Lu sublattice. To explain the discovered hysteresis in the temperature dependence of the 175Lu linewidth, a scenario of "crystallization of structural defects" is proposed, in which the defects of the Lu sublattice, disordered at room temperature, are transformed into a more symmetrical and stable configuration with decreasing temperature, apparently due to static distortions of the boron frame caused by the cooperative Jahn–Teller effect.
