Effects of Mn and Cu doping in La(T,Al)13 (T=Fe,Co) on crystal structure and magnetic properties

Structure and electrochemical properties of LaCo11−x−yNixMy (M=Fe, Mn and Al) compounds

“…It can be noticed from Table 1 that the lattice parameter and cell volume of compounds decrease with the substitution of Ni for Co and increase with the substitution of Al, Mn, Fe for Co, which is in agreement with that of Ref. [11], the variety of the lattice parameter and cell volume of compounds relates closely to the atom's radius of substituted element. Fig.…”

“…It shows that the substitution of Mn for Co in La(Co,Ni) 13 compounds is limited. The similar result is found in La(Co,Al) 13 compounds [11]. For the LaCo 11.4 Ni 0.8 Mn 0.8 sample, X-ray analysis shown that it consists mainly of 1:5 phase, also includes some 1:13 phase.…”

Study on the crystal structure of Al2Cu3Gd compound with XRPD

“…The intensity ratio RIR value is 1.29 by calculating the ratio of the highest diffraction peak intensity between Al 2 Cu 3 Gd and corundum. It was found that Al 2 Cu 3 Gd and Al 2 Cu 3 La (Guo et al ., 1997) have the same structure type ( P 6/ mmm , no. 191) by comparing the crystal structure information of Al 2 Cu 3 Gd with that of Al 2 Cu 3 La.…”

Crystal Structure of Al₂Cu₃Nd Ternary Compound

“…There are some compounds with the similar crystal structure of Al 2 Cu 3 Nd had been reported, such as Al 2 Cu 3 La(Y.Q. Guo, et al, 1997) [7], Al 2 Cu 3 Ce, Al 2 Cu 3 Yb (E. Bauer, et al, 1993) [8]. The properties of ternary compound in Al-Cu-Nd system had been seldom studied because of a small quantity of compounds have been developed.…”
