论文摘要
我们表明,可以使用自旋扭矩驱动的粘性磁化动力学来实现理想的备忘录 - 电阻与流动的电荷成正比的设备。后者可以在薄膜异质结构的旋转液态下实现,并具有沮丧的交换,在这种情况下,通过与玻璃过渡的接近度可以调节,而电流诱导的焦耳加热可有助于非挥发性操作和二阶的启发性功能对神经形态应用有益。在其他系统中,可以实现理想的回忆行为,这些系统以物理,电子或磁性自由度的粘性动力学为特征。
We show that ideal memristors - devices whose resistance is proportional to the charge that flows through them - can be realized using spin torque-driven viscous magnetization dynamics. The latter can be accomplished in the spin liquid state of thin-film heterostructures with frustrated exchange, where memristive response is tunable by proximity to the glass transition, while current-induced Joule heating facilitates nonvolatile operation and second-order memristive functionality beneficial for neuromorphic applications. Ideal memristive behaviors can be achieved in other systems characterized by viscous dynamics of physical, electronic, or magnetic degrees of freedom.
