High-Density 1R/1W Dual-Port Spin-Transfer Torque MRAM
Micromachines, 2022 Spin-transfer torque magnetic random-access memory (STT-MRAM) has several desirable features, such as non-volatility, high integration density, and near-zero leakage power. However, it is challenging to adopt STT-MRAM in a wide range of memory applications owing to the long write latency and a tradeoff between read stability and write ability.

Anomalous domain wall velocity and Walker breakdown in hybrid systems with anisotropic exchange [PDF]
, 2013 It has recently been proposed that spin-transfer torques in magnetic systems with anisotropic exchange can be strongly enhanced, reducing the characteristic current density with up to four orders of magnitude compared to conventional setups. Motivated by

Maximum Torque Density Limit for Surface-Cooled SPM Machines [PDF]
2020 International Conference on Electrical Machines (ICEM), 2020 The aim of this work is to find the maximum torque density limit of a surface cooled SPM machine. In this paper, an analytical and a FEM-based model are developed under some theoretical conditions. Both models consist of a magnetic and a thermal part, where they are used to calculate the torque and the temperature distribution, respectively. Each model
