Here we analyzed selected 1/1 Ho- and Sm-Au-Al AC phases in the range 53 < x < 71 with single crystal X-ray diffraction and magnetometry. We find that the Al/Au ordering behavior and associated structural changes with x are similar in both systems, and match that observed for RE = Gd, suggesting that the structural evolution with x is rather independent from the type of RE. On the other hand, the magnetic properties, and notably the type of long-range order obtained at large x, are strongly depending on the RE. Ho14AuxAl86-x samples with x = 61–71 consistently displayed a ferrimagnetic behavior whereas Sm14AuxAl86-x samples with x = 67 and 71 revealed AFM behavior.
Evolution of the magnetic properties with Au concentration x for RE14AuxAl86-x (RE = Gd, Tb, Ho, and Sm) quasicrystal approximants (ACs). The variation of the normalized Curie-Weiss temperature θp/dG and the magnetic state are plotted as function of the EDX Au concentration x (corresponding to electron per atom ratio, e/a) in 1/1 RE14AuxAl86-x ACs systems, summarizing previous reports and this work. The magnetic states of the ACs are SG = spin glass, FM = ferromagnetic order, and AFM = antiferromagnetic order. The dotted lines indicate the FM-AFM boundary for the individual RE-based samples. The green area includes both FM and AFM states, depending on the REs. [Display omitted]
