Van der Waals (vdW) materials with low crystalline symmetry and topological band structures, e.g., Weyl semimetals (WSMs), potentially serve as an outstanding system that may simultaneously realize field-free switching and high energy efficiency. Yet, the demonstration of these superiorities at room temperature has not been realized. Here, we achieve a field-free switching of perpendicular magnetization by using a layered type II WSM, TaIrTe\n                    <jats:sub>4<\/jats:sub>\n                    , in a TaIrTe\n                    <jats:sub>4<\/jats:sub>\n                    \/Ti\/CoFeB system at room temperature with the critical switching current density ~2.4 \u00d7 10\n                    <jats:sup>6<\/jats:sup>\n                    A cm\n                    <jats:sup>\u22122<\/jats:sup>\n                    . The field-free switching is ascribed to the out-of-plane SOT allowed by the low crystal symmetry. Our work suggests that using low-symmetry materials to generate SOT is a promising route for the manipulation of perpendicular magnetization at room temperature.\n
