The breaking of parity and time-reversal symmetry in two-dimensional Fermiliquids gives rise to non-dissipative transport features characterized by theHall viscosity. In magnetic fields, the Hall viscous force directly competeswith the Lorentz force, since both mechanisms contribute to the Hall voltage.In this work, we present a channel geometry that allows us to uniquelydistinguish these two contributions and derive, for the first time, theirfunctional dependency on all external parameters. We show that the ratio of theHall viscous to the Lorentz force contribution is negative and that its modulusdecreases with increasing width, slip-length and carrier density, while itincreases with the electron-electron mean free path of our channel. In typicalmaterials such as GaAs the Hall viscous contribution can dominate the Lorentzsignal up to a few tens of millitesla until the total Hall voltage vanishes andsubsequently is overcome by the Lorentz contribution. Moreover, we prove thatthe total Hall electric field is parabolic due to Lorentz effects, whereas theoffset of this parabola is characterized by the Hall viscosity. Hence, ourresults pave the way to measure and identify the Hall viscosity via both globaland local voltage measurements.
