“…5. The isotropic ADP are related to the mean-square displacement amplitudes < U iso > of the corresponding lattice sites as [36] B iso = 8π U 2 iso + B sta (3) where B sta is the component of the thermal parameter caused by the presence of static disorder in the lattice. Within the Debye model the U iso (T ) is given as [37] < U 2 iso >=…”

The quasi-binary system SmGa2–SmAl2 at 600ºC

“…Isothermal sections of the phase diagrams of ternary systems R-Ga-Al (R -rare-earth metal) have been constructed for the following rare-earth metals: Y, La, and Ce at 400°C in the region 0-33.3 at.% R [1,2], La at 400°C over the whole concentration range [3,4], Gd at 800°C in the region 20-100 at.% Gd [5,6], Ho at 500°C and 800°C in the region 25-33.3 at.% Ho [3]. For R = Ce [7], Nd [8,9], Eu [10], Gd [11], Er [8,9], Tm [12,13], and Yb [10,14] the quasi-binary sections RGa 2 -RAl 2 have been investigated. In some systems, alloys of the equiatomic compositions RGaAl were synthesized and investigated by X-ray diffraction.…”
