The magnetic properties of binary Gd-Cd and ternary Gd-Au-Ge crystals obtained from the newly introduced low-melt peritectic formation (LMPF) synthesis method were investigated. This method consists of a rapid quenching of the metallic melt followed by an annealing treatment at a relevant temperature. In the first system, both quasicrystal (QC) and approximant crystal (AC) phases can be stabilized, whereas only the AC phase is obtainable in the pseudo-binary Gd-(Au-Ge) system. The magnetic properties of the crystals obtained from LMPF for each system are compared to those of larger single grain crystals obtained from the self-flux (SF) method.
研究了通过新引入的低熔包晶形成（LMPF）合成方法获得的二元Gd-Cd和三元Gd-Au-Ge晶体的磁性。该方法包括对金属熔体进行快速淬火，然后在相关温度下进行退火处理。在第一个体系中，准晶（QC）相和近似晶体（AC）相都可以被稳定下来，而在伪二元Gd-(Au-Ge)体系中只能获得AC相。将通过LMPF方法获得的每个体系晶体的磁性与通过自熔剂（SF）方法获得的较大单晶的磁性进行了比较。
