Influence of Co substitution on magnetic properties and thermal expansion of Nd6Fe13Si intermetallic compound

Site preferences and lattice vibrations of Nd 6 Fe 13 − x T

“…According to the results for the occupancy behaviors of T , the lattice parameters of the Nd 6 Fe 13−x T x Si are calculated when T atoms are in 4d or 16l 2 sites. Table 1 shows the results of Nd 6 Fe 13−x T x Si obtained from both the experiments [9,17] and calculation. Atomic parameters have also been investigated based on the inverted pair potentials (Table 2).…”

“…[8] Experimentally, there have been studies of replacing Fe atoms in Nd 6 Fe 13 Si by other transition elements, and some of them had promising effects. [9,10] The information about which crystalline site is actually replaced is helpful in understanding the mechanism of the property being changed by substitution. There have been numerous experimental studies devoted to identifying the site occupation.…”
