摘要
We investigate the dynamics of an isotropic spin ladder with two ferromagnetic legs coupled antiferromagnetically and construct spin soliton solutions. We demonstrate the sharing of energy among the legs via rung and thus soliton exhibits switching between bistable states leading to the possibility of construction of logic gates.
