用超声测量方法研究了准晶GdCd6的低温和弹性性质。在主要弹性常数的温度和磁场依赖关系中观察到了显著的弹性反常，这很可能与低温下连续出现的多次磁相变有关。根据实验数据，建立了磁场-温度相图。在零磁场中，至少存在四个相。然而，在H//磁场作用下的相图。
Low-temperature and elastic properties of the quasicrystal approximant GdCd 6 have been investigated by means of an ultrasonic measurement. Salient elastic anomalies were observed in the temperature and magnetic field dependence of the principal elastic constants, most probably being associated with the successive multiple magnetic phase transitions showing up at low temperatures. Based on the experimental data, a magnetic field vs temperature phase diagram was constructed. In a zero magnetic field, at least four phases appear to exist. However, the phase diagram both for the magnetic field applied for H//
