We developed a frequency-stabilized diode laser using magnetically induced circular dichroism. From a spectroscopic study on Rb- $_{2}$ line, the most stable Doppler-broadened and Doppler-free lines were determined to be the transition from g=2 ground state of $^{85}$ Rb and the crossover resonance from g=3 ground state to e=3 and 4 excited states of $^{85}$ Rb respectively. Furthermore, we measured the fluctuation of the laser locked to the Doppler-free line to be 50kHz/8hour and thus revealed the applicability to a several-hours stabilization. The developed laser can be used as a reference laser for frequency stabilization system for multiple tunable lasers for RIMS analysis.
