Spin-orbit torque （SOT）,as a promising writing method for magnetic random-access memory （MRAM）,has garnered widespread interest for over a decade [1].Heavy metals,such as β-W,have been broadly adopted as spin current sources,but suffer from phase change at a limited thickness,resulting in a dramatic reduction of the charge-tospin conversion efficiency θSH[2].The thickness limitation leads to stringent etching conditions and large distribution among devices,posing challenges for simultaneously satisfying SOT efficiency,etching-stop margins,and back-end-ofline （BEOL） compatibility.

纬学宇宙论的思想方法是由天及人。从其发展过程来看,宇宙本体论、生成论和运行论渐次演化,共同组成宇宙建构论。从其发展路线来看,建构论分为自然宇宙物质性演变和人文宇宙精神性演变。自然宇宙演变以“气”本体为起点,“五气渐变”生成宇宙,并按照一定的“度”“数”规律运行。人文宇宙演变与之大致同步,所含《诗》学思想先论诗与道的本原,再论诗的构思过程与发生原理,而后及于诗学周期论.
