Magnon torques can potentially circumvent this issue, as it enables the transport of spin angular momentum in insulating magnetic materials.

The magnon torque efficiency is estimated to be \u22120.134 using in\u2010plane second harmonic Hall measurements. Using magnon torques, perpendicular magnetization switching of CoFeB is achieved, with a critical switching current density of 4.09 \u00d7 10\n                    <jats:sup>7<\/jats:sup>\n                    A\u00a0cm\n                    <jats:sup>\u22122<\/jats:sup>\n                    .
