"The Critical Behaviour and Magnetism of MnCoGe0.97Al0.03 Compounds" by Abdul Rashid Abdul Rahman, Muhamad Faiz Md Din et al.
The critical behaviour associated with the field-induced martensitic transformation heav-ily relies on the vacancy and transition of the magnetic phase in MnCoGe based-compounds. Due to this revelation, an intensive investigation was brought forth to study the substitution of Ge (atomic radius = 1.23 Å) by Al (atomic radius = 1.43 Å) in MnCoGe0.97Al0.03 alloy compound. The room-temperature X-ray diffraction indicated that the reflections were identified with the ortho-rhombic structure (TiNiSi-type, space group Pnma) and minor hexagonal structure (Ni2In-type, space group P63/mmc). The substi...
