However, the interplay between electron quantum interference and electronic magnetochiral anisotropy, a nonreciprocal resistance in chiral systems, remains largely unexplored. Here, we report the observation of magnetoresistance oscillation embedded within a nonreciprocal transport signal. Electrically tunable, B-periodic oscillation in the second-harmonic voltage is discovered in the out-of-plane magnetoresistance in 1T-TiSe₂ thin flakes. We attribute this oscillation to the Altshuler-Aronov-Spivak (AAS) interference of surface states confined to the chiral domain walls of 1T-TiSe₂. Analysis using the AAS model reveals effective cross-sectional areas of chiral domains ranging from 1180 to 1880 nm². Our work establishes a novel method for probing surface states in the presence of conductive bulk states.
