AbstractIn a Dirac semimetal, charges flow between two Weyl nodes when electric and magnetic fields (E||B) are parallel to each other manifesting interesting physical properties such as negative longitudinal magnetoresistance (NLMR), planar Hall effect (PHE). A co‐existence of weak antilocalization (WAL) is observed with large NLMR and an unusual Hall resistance with (B||E) configuration, at the conducting interface of LaVO3 (LVO) and KTaO3 (KTO). The full‐width half maxima of the depth of the conducting channel at the interface is estimated to be around 10 nm by using spectroscopy techniques of photoluminescence and time‐correlated single‐photon counting: suggesting a quasi‐2‐dimensional nature of the conducting electrons. The PHE exhibits oscillatory behavior as a function of the angle between E and B. Very similar temperature dependence of NLMR and PHE suggest a strong correlation among them.
