Heavily Damped Precessional Switching with Very Low Write-error Rate in Elliptical-cylinder Magnetic Tunnel Junction
Rie Matsumoto, Shinji Yuasa, Hiroshi Imamura
Voltage-induced dynamic switching in magnetic tunnel junctions (MTJs) is a writing technique for voltage-controlled magnetoresistive random access memory (VCMRAM), which is expecte…
Distribution of write error rate of spin-transfer-torque magnetoreistive random access memory caused by a distribution of junction parameters
Hiroshi Imamura, Hiroko Arai, Rie Matsumoto
Distribution of write error rate (WER) of spin-transfer-torque magnetoreistive random access memory (STT MRAM) caused by a distribution of resistance area product and anisotropy co…
Precession dynamics of a small magnet with non-Markovian damping: Theoretical proposal for an experiment to determine the correlation time
Hiroshi Imamura, Hiroko Arai, Rie Matsumoto +2
Recent advances in experimental techniques have made it possible to manipulate and measure the magnetization dynamics on the femtosecond time scale which is the same order as the c…
Large angle precession of magnetization maintained by a microwave voltage
Hiroshi Imamura, Rie Matsumoto
Effects of a microwave voltage on magnetization precession are analyzed based on a macrospin model. The microwave voltage induces the oscillating anisotropy field through the volta…
Low power switching of magnetization using enhanced magnetic anisotropy with short-voltage-pulse application
Rie Matsumoto, Hiroshi Imamura
A low power magnetization switching scheme based on the voltage control of magnetic anisotropy (VCMA) is proposed. In contrast to the conventional switching scheme using VCMA, wher…
Impact of spin transfer torque on the write error rate of a voltage-torque-based magnetoresistive random access memory
Hiroshi Imamura, Rie Matsumoto
Impact of spin transfer torque (STT) on the write error rate of a voltage-torque-based magnetoresistive random access memory is theoretically analyzed by using the macrospin model.…
