摘要：
Charge flowing in a thin film of the topological insulator bismuth selenide at room temperature can lead to spin accumulation in the insulator and a resultant strong spin-transfer torque on an adjacent thin film of ferromagnetic nickel–iron alloy, potentially offering a means of controlling the orientation of the alloy’s magnetization.
