The dc magnetization of single crystalline ZnMn2As2 is studied using an rf‐SQUID. It is found that the crystals are anisotropic, show a ferromagnetic transition around T = 310 K, a helical magnetic phase below T = 110 K, and there is evidence of a strong spin‐glass behavior below T = 33 K. The spin‐glass phase is studied from zero‐field cooled (ZFC) and rémanent magnetization experiments. An irreversibility line (de Almeida‐Thouless line) is clearly observed for both principal orientations of the crystal and a comparison is made between the magnetic moment relaxation measured using the ZFC and the rémanent methods. |
