ABSTRACT |
ase of ft. We obtained the energy gap Parameter 2$Delta$(4.2 K) = 54.4~64 meV, and corresponding1y $Delta$/ $k_{B}$ $T_{c}$ $^{zero}$=7.36~10.14, larger than the BCS value. The lattice constant c and critical temperature $T_{c}$ $^{zero}$ decrease with increase of $chi$$_{L}$. ᬊ吀 Ѐ㘷〻ഀ䵡湵晡捴畲楮最 |
