Single-crystal growth and magnetic anisotropy in PrFe₂Ga₈

Single crystals of PrFe₂Ga₈were successfully grown by using Ga self-flux. PrFe₂Ga₈crystallizes in the CaCo₂Al₈-type orthorhombic structure with the space groupPbam(no. 55). By combining the results from the magnetic-susceptibility, specific-heat, and resistivity measurements, we show that PrFe₂Ga₈exhibits a magnetic order at 14 K. ForH//c, the antiferromagnetic order can be suppressed by magnetic fields. However, the magnetic order is robust against magnetic fields forH⊥c. Our results provide basic physical properties of PrFe₂Ga₈and will help to further understand the magnetism in this system.
