The quantum entanglement of spin states in molecular magnets has important applications in quantum information technologies. Currently, qubit models based on magnetic molecules are being developed to advance quantum computation and communication technologies. In this study, we examine a molecular magnet consisting of a spin-1/2 triangular configuration, with a Katsura-Nagaosa-Balatsky(KNB) mechanism to couple spin degrees of freedom with an external electric field. Thanks to the KNB mechanism, the system allows for extensive control over quantum entanglement through the magnitude and direction of the electric field. By utilizing a rotating configuration of the KNB-coupled electric field where the field magnitude remains fixed while its direction rotates-the controllable transfer of bipartite entanglement between different pairs of spins in the model is demonstrated.
