We give a large class of supersymmetric Janus solutions in -deformed (dyonic) SO(8) maximal gauged supergravity with . Unlike the purely electric counterpart, the dyonic SO(8) gauged supergravity exhibits a richer structure of vacua with supersymmetries and SO(8), U(3), and SU(3) symmetries, respectively. Similarly, domain walls interpolating among these critical points show a very rich structure as well. In this paper, we show that this gauged supergravity also accommodates a number of interesting supersymmetric Janus solutions in the form of -sliced domain walls asymptotically interpolating between the aforementioned geometries. These solutions could be holographically interpreted as two-dimensional conformal defects within the superconformal field theories (SCFTs) of ABJM type dual to the vacua. We also give a class of solutions interpolating among the SO(8), and U(3) vacua in the case of which have not previously appeared in the presently known Janus solutions of electric SO(8) gauged supergravity.
