“…This new component can be attributed to ZrNi 3 by comparing the results reported from our recent PAC investigations in ZrNi 3[33]. It is known that ZrNi 3 was formed by the peritectoid reaction (Zr 2 Ni 7 +Zr 8 Ni 21 →ZrNi 3 ) at 1193 K[20] and at 1261 K[21].The predominant phase due to ZrNi (63%) is found to be produced here which was first observed at 973 K in the sample. Appearance of ZrNi as a secondary phase in the synthesized Zr 9…”

“…The theoretically optimized structure parameters together with the experimental values obtained from earlier [16,21] and present X-ray diffraction measurements are shown in Table 3. We can see that a lattice constants overestimate the experimental ones for about 1%, while the c lattice constants underestimate the measured ones for about 2%.…”

“…Also, in case of Zr 9 Ni 11 , unusual magnetic properties were reported by Provenzano et al [15]. Its crystal structure is known to be body-centered tetragonal with space group I4/m [8,14,[16][17][18][19][20][21] which is reported to be isostructural to Zr 9 Pt 11 [18,22,23]. The lattice parameters of Zr 9 Ni 11 were found to be a = 9.88(1) Å and c = 6.61(1) Å [16].…”

Crystalline phases formed in stoichiometric Zr 9 Ni 11 and Hf 9 Ni 11 have been studied by perturbed angular correlation (PAC) spectroscopy, XRD and TEM/SAED measurements. In Zr 9 Ni 11 , the phases Zr 9 Ni 11 (∼89%) and Zr 8 Ni 21 (∼11%) have been found at room temperature from PAC measurements. At 773 K, Zr 9 Ni 11 partially decomposes to Zr 7 Ni 10 and at 973 K, it is completely decomposed to ZrNi and Zr 7 Ni 10 .In Hf 9 Ni 11 , a predominant phase (∼81%) due to HfNi is found at room temperature while the phase Hf 9 Ni 11 is produced as a minor phase (∼19%). No compositional phase change at higher temperature is found in Hf 9 Ni 11 . Phase components found from XRD and TEM/SAED measurements are similar to those observed from PAC measurements. Electric field gradients in Zr 9 Ni 11 and Hf 9 Ni 11 have been calculated
