| Abstract(in English) | An optically pumped K-Rb hybrid atomic magnetometer is expected to be applied to biomagnetic measurements for its spatial homogeneity of the sensor property inside a cell. However, since the property varies depending on the density ratio of potassium and rubidium atoms, the otimization of the density ratio is essential. In this study, by using a numerical model considering the spatial distribution of the spin polarization, we confirmed the calculation results have a good agreement with the experimental data without depending on the densities of the alkali metal atoms, and determined the optimal density ratio to maximize the output signal and enhance its spatial homogeneity. |
