In this work, we report the successful synthesis of a polycrystalline, binary compound ErIr 3 , forming a macroscopic coexistence of two different cubic structures (AuBe 5 -type and AuCu 3 -type). The magnetic properties of two polymorphs could be distinguished by means of different measurement techniques. The detailed study of dc magnetization and heat capacity behaviour confirm that the phase with the cubic AuBe 5 -type structure orders ferromagnetically below 5.2 K, while the AuCu 3 -type phase remains paramagnetic down to 2.5 K. The presence of a glassy state in this compound is manifested in the frequency dependent ac susceptibility measurement, magnetic relaxation and magnetic memory effect.

ErIr 3双晶相的非平衡磁性能

在这项工作中，我们报告了多晶二元化合物ErIr 3的成功合成，形成了两种不同立方结构（AuBe 5型和AuCu 3型）的宏观共存。可以通过不同的测量技术来区分两个多晶型物的磁性。直流磁化和热容量行为的详细研究证实，具有立方AuBe 5型结构的相在5.2 K以下铁磁有序，而AuCu 3型相在低至2.5 K时仍保持顺磁性。在此存在玻璃态该化合物表现在频率相关的磁化率测量，磁弛豫和磁记忆效应中。
