摘要：
The effect of both spin-orbit interaction and Zeeman interaction on a thermodynamic equilibrium (persistent) current in a one-dimensional ballistic ring of correlated electrons is considered at arbitrary temperatures. It is shown that the change of the number of spin excitations in a ring due to the Zeeman effect affects considerably the persistent current. (C) 2000 Elsevier Science B.V. All rights reserved.
