Abstract

| Melting temperatures T-m of six heavy rare earth metals are well established experimentally. Here, a close correlation is displayed between these values T-m and the de Gennes factor (xi below), which is proportional to the product of ( g - 1)(2) with total angular momentum values J ( J + 1). We thereby exhibit a tendency of a plot of T-m versus.xi(-1) to saturate at the largest., this corresponding to Gd of the six selected elements. Second, following Chikazumi's book, it is stressed that the N eel temperatures T-N of the remaining five metals display empirically a good linear correlation with xi(2/3). Finally, the monovacancy formation energy is briefly considered in relation to the thermal energy k(B)T(m), the ratio E-v/k(B)T(m) being of order 10 in other known cases. |
