the area of this shoulder peak with higher amount of analytes can also be explained by similar arguments. Although relative interference of the ions was reported by various researchers [ 36 ], but in most of the previous studies electrodes were calibrated by using one type of ionic species at a time in the test solution. The obvious result was in the form of linear calibration. On the other hand, mechanistic approach is required when more than one type of analytes are present in the real sample solution.

% and 32.5 % for FeB, Fe 2 B and Fe 3 B, respectively ( Fig. 3 ). This enhanced N (E f ) is derived entirely from the Fe 3d states, with negligible contribution from the B 2p states. Following the above arguments we may predict that the appearance of superconductivity in Fe x B under pressure is similar to the case of iron that undergoes a transition to superconducting phase above 30 GPa when it loses its magnetic moment [ 31 ]. It is easy to observe that the magnetic moment decreases with increasing pressure.

can be again explained by the appearance of the second phase. The restoration of the structural quality for x = 0.5 can be explained on the basis of the argument given already by Branford et al. [ 52 ]. The authors in question noted that the cation structural unit ( Fig. 8 therein) was built of 4 cations which stabilized the configurations of 1:3 or 2:2 (1:1). In our case, the x = 0.5 sample is an example of 1:3 ratio (0.5 Ni:1.5 Mn).
