Based on the phase time definition,we study theoretically the transmission coefficients and the spin-tunneling time in parabolic-well magnetic tunneling junction with a tunnel barrier in the presence of Rashba spin-orbit interaction. The significant quantum size, quantum coherence, and Rashba spin-orbit interaction are considered simultaneously. It is found that the tunneling time strongly depends on the spin orientation of tunneling electrons. We also find that as the length of the semiconductor increases, the spin tunneling time shows curved increase. It exhibits useful instructions for the design of spin electronic devices.
