  四甲基铵三溴镉晶体中铁电相变的79Br核四极杆共振研究

  摘要：

  在铁相和顺电相中测量了四甲基三溴镉铵中的 79 Br 核四极杆共振频率和自旋晶格弛豫时间 T 1 。铁电相中共振线分裂的幅度取决于温度为 Δν∝ (T c - T ) 0.12 。在转变点附近观察到 T 1 的急剧下降，这归因于与铁电相变相关的临界波动。

  Results of an experimental research of phase equilibrium in ternary systems MX2-NR4X-H2O [M = Cd(II), Cu(II), Co(II), Mg(II); X = Cl, Br; R = Me, Et, Bu] at 25A degrees C were reported. A comparative analysis of compositions of solid compounds and regions of their crystallization, which are equilibrium with liquid phase, was conducted. An effect of hydration, association of salts of quaternary ammonium and acido complexation of ions of d-elements on the formation of the complex and double salts in the systems was presented.

  The effect of hydrostatic pressure on the low-temperature structural phase transitions in N(CH3)(4)XBr(3) (X: Mn, Ni, Cd) has been studied. The I-II transition temperatures of N(CH3)(4)MnBr3 (140 K at atmospheric pressure), N(CH3)(4)NiBr3 (135 K), and N(CH3)(4)CdBr3 (161 K; the ferroelectric Curie temperature) increase linearly with increasing pressure with coefficients of 0.075K K/MPa, 0.092 K/MPa, and 0.086 K/MPa, respectively. As pressure increases the II-III transition temperature of N(CH3)(4)NiBr3 (97 K) decreases with a pressure coefficients of -0.07 K/MPa. The results are compared with those previously reported for N(CH3)(4)XCl(3)-type crystals (X: Mn,Cd) and discussed.
