At zero field a sharp peak of the specific heat is observed at TN = 2.2 K, implying a phase transition. The magnetic susceptibility in a field applied along 100, which is a magnetically easy direction, remains almost the same value below TN. The longitudinal elastic modulus, C11, shows an obvious hardening at TN, and TN decreases up to 0.4 T as the magnetic field applied along 100 increases, suggesting an antiferromagnetic ordering. In the magnetic field dependence of C11 at 0.5 K, we discovered two abrupt softenings at 0.25 T and around 0.47 T, proposing that the antiferromagnetic phase boundary closes around 0.47 T in the field applied along 100. Other phase boundary exists around 0.25 T in the ordered state.
