Everspin Technologies today announced an amendment of it’s Spin-transfer Torque (STT-MRAM) joint development agreement (JDA) with GLOBALFOUNDRIES® (GF®), the world’s leading specialty foundry.
“Spin-transfer Torque MRAM technology is an ideal candidate for radiation hard FPGA devices due to its persistence and inherent radiation immunity, said Sanjeev Aggarwal, President & CEO of Everspin. “We are excited to work with the other partners on this program to develop reconfigurable, FPGA...
We review our recent work on spin-transfer torque (STT) effects in single-crystalline, all-metal nanopillars. The experiments deal with current-driven magnetization switching and excitation of steady-state high-frequency magnetic oscillatory modes. The interplay between the magnetocrystalline anisotropy ...

上式中第一项为磁矩在有效场作用下的进动,第二项为磁化强度向其平衡方向的弛豫(relaxation),或称为Gilbert damping torque,第三项代表STT,即其他的来源于能量密度,尤其是电流诱导产生的转矩: \vec T=\tau_{\text{FL}}\vec m\times\vec \zeta+\tau_{\text{DL}}\vec m\times\left(\vec m\times \vec ...
畴壁内部不同位置的磁化强度具有不同的方向,相邻磁化强度之间存在一定的夹角,当存在自旋极化电流时,被极化的电子 具有特定指向的自旋,当它们运动至畴壁处,由于电子的自旋与背景磁化强度之间并不平行,它们会发生角动量的转移,即产生自旋转移矩,这个矩一方面使得畴壁内部背景磁矩的方向发生偏转(偏向极化电子的自旋),另一...
