Our measurements suggest that in low applied magnetic field it undergoes an antiferromagnetic transition below TN ~ 9 K. When compared with the ground state of CuFeSb, recently reported 111-type ferromagnetic material (TC ~ 375 K), it has important implication with regard to the nature of Fe-Fe magnetic interaction in Fe-As materials.
