摘要：
We present results of magnetization measurements showing that the magnetic response of the antiferromagnetic state of SmMn2Ge2 depends on the path used in the field (H)-temperature (T) phase space to reach this state. A distinct signature of metastability is observed in this antiferromagnetic state when obtained via field-cooling/field-warming paths.
