A new proposal is given to control local magnetic field in a molecular junction. In presence of finite bias a net circular current is established in the molecular ring which induces a magnetic field at its centre. Allowing a direct coupling between two electrodes, due to their close proximity, and changing its strength we can regulate circular current as well as magnetic field for a wide range, without disturbing any other physical parameters. We strongly believe that our proposal is quite robust compared to existing approaches of controlling local magnetic field and can be verified experimentally.
提出了一种在分子结中控制局域磁场的新方案。在有限偏压下，分子环中建立了净的环形电流，从而在环中心产生了磁场。通过允许两个电极由于靠近而直接耦合，并改变其强度，我们可以在不干扰任何其他物理参数的情况下，广泛调节环形电流和磁场。我们坚信，与现有的控制局域磁场的方法相比，我们的方案具有较强的鲁棒性，可以通过实验验证。
