Spin-density-wave glass state in Cr-based alloys with 3d impurities

A spin-density-wave (SDW) glass state has been found in Cr alloys. Magnetization measurements in ZFC and FC states have revealed two types of magnetic irreversibility (MI). The first one is caused by a 'local SDW'. Depending on the electron concentration of impurity a temperature of divergence of MZFC(T) and MFC(T), Ti, can be either below or above TN. The second type of MI is due to the deformation of the soliton wall of the SDW domains and can be realized only in Cr alloys with an incommensurate SDW structure just below TN
