摘要：

The goal of this study is to determine optimal conditions of optically pumped atomic magnetometers using a hybrid cell of potassium and rubidium atoms. We theoretically investigated the properties of the magnetometers and considered the optimal density ratio of potassium and rubidium atoms. We found that the experimental results agreed well with the theoretical estimations and the density ratio of potassium and rubidium atoms should be around 200 to achieve the highest sensitivity.
