“…As shown from Table 3, the averaged volume V Fe and V B are almost unchanged with metalloid concentration. In addition, those quantities are close to the volumes given as 4pr 3 Fe =3 and 4pr 3 B =3, respectively. Here r Fe , r B are the radius of iron and boron, respectively.…”

“…Recently voids (or free volume) in amorphous solid such as SiO 2 , Al 2 O 3 and Fe x B 100Àx continue to be of interest from both technological and scientific points of view [1][2][3][4][5][6][7][8][9][10]. Plenty of experimental data accumulates that voids are involved in the atomic transport, the thermal stability and the gas solubility [17][18][19][20][21].…”

“…structure of nickel. This disorder might arise, in the above-cited structural model [9], from the regions where the local order is pseudoicosaedral : these ones induce stresses in the neighbouring regions with f.c.c. structure, which extend over wide zones for this metalloid concentration.…”

“…Recently a structural model for amorphous Ni1-xP x alloys was proposed, with a local order varying with increasing x [9]. Starting from a f.c.c.-like structure at lower x values, it was shown that for x > 0.15, a hexagonal ordering of pseudo-dodecahedra gradually changes into a continuous random packing of relaxed dodecahedra [10]. The f.c.c.-like structure was actually observed by EXAFS studies on electrodeposited NiP alloys [11].…”

The influence of various annealings on the magnetization of a partially disordered Ni91P9 alloy has been investigated. The magnetic moment σ*o,o and the Curie temperature T c are found to vary linearly with the annealing temperature T a up to Ta = 523 K and the alloy behaves like a weak ferromagnet. With Ta > 573 K, the (200) reflexion of the f.c.c. nickel appears in the X-ray patterns and a sharp increase in T c and σ*o,o is observed. These results agree with previous thermomagnetic data which showed the alloy to be completely crystallized in a mixture of pure nickel and Ni3P alloy after heating to T a = 773 K. Anomalous thermal variation of the magnetization is observed below 50 K, as previously observed by other researchers

“…Their electrical and optical properties depend on the electronic structure, which is governed by medium-and short-range order of atomic/ions position. Structure analyses of amorphous have been done chiefly by extended X-ray absorption fine structure (EXAFS) [1] , although X-ray diffraction [3] and high-resolution transmission electron microscopy (HRTEM) [4] are used. EXAFS gives local structures such as bond distances of the nearest and the coordination number which are average of the specimen size.…”
