- 論文の詳細を見る
Thermodynamic properties of the bond-diluted Heisenberg ferromagnet in twodimensions are studied within the framework of the modified spin-wave theory. It isshown that the renormalized exchange (2 m - l )J, m being the bond concentration, ap-pears in place of J in the expressions of various thermodynamic quantities in theperfectly bonded case, consistent with the result obtained in the Monte Carlo calcula-tion at low temperatures.[modified spin wave theory,two dimensional Heisenberg ferromagnet, bond dilu- ll Lion, thermodynamic propertiesl
