  Non-reciprocal charge transport that is strongly associated with the
structural or magnetic chirality of the quantum materials system is one of the
most exotic properties of condensed matter physics. Here, using magnetic alloys
film Pt2MnGe, we have realized the large non-reciprocal charge transport up to
room temperature, which roots in the organic combination of chirality dependent
carrier scattering and special magnetic configurations. In this framework, the
conduction electrons are scattered asymmetrically by the emerging non-zero
vector spin chirality under in-plane magnetic field, resulting in robust
non-reciprocal response. More astonishingly, the vector spin chirality in
Pt2MnGe film can be reversed by a spin-polarized current through spin Hall
effect in a junction with Pt layer. Our work resolves the general limitation of
non-reciprocal charge transport to cryogenic temperatures, and paves the way
for extending its applications in the emerging field of chiral spintronics.
