Abstract

A magnetic order of the quasicrystal approximant Au70Al16Tb14 was investigated via single crystalline neutron diffraction experiments. In spite of some differences in the macroscopic magnetic properties compared with Au72Al14Tb14, the whirling antiferromagnetic structure similar to Au72Al14Tb14 was found. The robustness of the magnetic structure suggests the orientation of the magnetic moment dominated by easy-axis anisotropy of Tb. In addition, the critical exponent β indicates a mean field nature of the magnetic transition.
