We investigated the characteristics of the nonlinear magneto-optic effect (NMOE) depend on the transitions, the laser intensity and the temperature of the vapor cell, in the $D_1$ transition of $^{87}Rb$ atoms by using the Rb vapor cell contained with buffer gas of Ne 6.7 kPa. The size and the width of NMOE signal were increased according to the light intensity and temperature in the transition of F=2$\to$F'=2. However, In the case of using the F=2$\to$F'=1 transition, the size of the signal could be increased according to the light intensity without additional broadening of the width. We confirmed that the sensitivity of detecting small magnetic flux improved in this transition, and explained these effects by the different of the CPT configuration between Zeeman sublevels. At the optimal condition in experiment, the sensitivity of this system was evaluated less then $70pT/\sqrt{Hz}$.

소형 루비듐 원자시계를 만들기 위해 원자에서의 CPT(coherent population trapping) 현상, 유도 라만 산란(SRS: Stimulated Raman Scattering), 루비듐 메이저 등 다양한 방법들이 소개되고 있다$^{(1, 3)}$ . 본 연구에서는 루비듐 원자 주파수 표준기를 위해 루비듐 셀을 이용한 마이크로파 주파수 표준기(즉, 원자시계)에 관한 연구를 수행하였다. 루비듐 셀을 이용한 원자시계는 가격이 저렴하고 부피가 작아 휴대용으로 적합하다. 따라서 정보통신 분야에서 동기 신호 발생기에 사용되는 등 다양한 응용분야를 갖고 있다.
