Abstract
Single crystals ofLnRu2Ga8andLnCo2Al8(Ln= La and Pr) were grown using a Ga/Al self-flux method. An orthorhombic CaCo2Al8-type structure with space groupPbam(No.55) of them was identified by x-ray diffraction. LaRu2Ga8and LaCo2Al8are Pauli paramagnetic down to 2 K, while PrRu2Ga8and PrCo2Al8show antiferromagnetic (AFM) order at 2.5 and 5 K, respectively. Strong magnetic anisotropy in PrRu2Ga8and PrCo2Al8single crystals was found by an anisotropic magnetic measurement. The field-induced FM state was observed in both PrRu2Ga8and PrCo2Al8forH||c. However, in the case of H⊥c, the AFM state is robust. The strong magnetic anisotropy in PrRu2Ga8FM and PrCo2Al8is due to their anisotropic magnetic interactions that FM interactions are dominant in the case ofH||cwhile AFM interactions forH⊥c.
