摘要

In this study we report results of X-ray diffraction and dc magnetization measurements inMn_(1-x)Al_(1-y)Cu_(x-y) alloys in the k phase which has a B2 (CsCl-type) structure. Increasing Cu doping not only weakens the ferromagnetic order and strongly affects Curie temperature (TC) but also imposes a competition mechanism between ferromagnetic and ferrimagnetic spin correlations which induces the appearance of cluster spinglasslike phase at low temperatures.
