“…However, for the degree of ordering, contradictory results were found: while some reports indicate an increase of the ordering degree with the addition of Mn [12,15], some others report the opposite [17,18]. Also, magnetic properties such as the saturation magnetization M s [14,15,19,20] and the magnetocrystalline anisotropy MCA [12,15,18e20] have different evolution with Mn content according to different investigators.…”
