We have succeeded in coating an aluminum oxide thin film of inorganic-organic hybrid on the inner wall of the cell of an optically pumped atomic magnetometer using spin polarization of alkali metal atoms by a unique room temperature molecular layer deposition method. The relaxation time of polarized spin was investigated by using the pump probe method, and it was revealed that the relaxation time of spin polarization can be significantly improved and the relaxation prevention effect can be remarkably exhibited as compared with the case without coating.
We developed molecular layer deposition method of atomically thin hybrid polymer film for the first time by developing atomic layer deposition method with sequential surface chemical reactions in order to minimize the effect of the dipole-dipole interaction between the electron spin of alkali metal atoms and the nuclear spin of the atoms in the glass of the cell. We controlled film thickness of polymer thin film precisely and finally aimed at improving the sensitivity of the optically pumped atomic magnetometer. In the presentation, we report on the relaxation time of spin polarization by atomically thin hybrid polymer film with laser pump-probe method.
