| contents | We present a scheme to enhance two different magnon modes entanglement in cavity magnomechanics via nonlinear effect. The scheme demonstrated that nonlinear effects enhance entanglement of the two magnon modes. Moreover, the entanglement of the two magnon modes is also significantly enhanced by microwave parametric amplification (PA) and magnon self-Kerr nonlinearity. Not only dose nonlinear effect enhances the strength of entanglement, but it also increases the robustness of entanglement against temperature. Our proposed scheme plays an important role in the research of fundamental theories of quantum physics and quantum information processing theory. |
