Abstract

We carried out precise magnetization measurements in an Al70Pd20Mn10 quasicrystalline system using a high-quality single crystal. A strange phenomena was observed at room temperature, which was a difference between zero field cooled and field cooled magnetization below 290 K. The thermoremanent magnetization also disappeared at 290 K. These experimental results suggest the forming of ferrimagnetic Mn ions clusters in Al70Pd20Mn10 below 290 K. In addition, high field magnetization in the temperature range between 4.2 and 30 K up to 12 T was also measured to investigate the anisotropic molecular field between clusters.
