Generating Unconventional Spin‐Orbit Torques With Patterned Phase Gradients in Tungsten Thin Films
Advanced Materials, EarlyView.ABSTRACT A key aim in spintronics is to achieve current‐induced magnetization switching via spin‐orbit torques without external magnetic fields. For this, the focus of recent work has been on introducing controlled lateral gradients across ferromagnet/heavy‐metal devices, giving variations in thickness, composition, or interface quality.

Solar irradiance variability [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractWe study solar irradiance variability. The current generation of models show that the irradiance since then has increased by between 0.9 and 1.5 W m−2.

Eos, Transactions American Geophysical Union, 1983 The planned repair in orbit by NASA of the Solar Maximum Mission (SMM) in April 1984 provides an excellent opportunity for improved observations of the sun. In retrospect the solar‐terrestrial research community should have organized new programs before the 1980 launch of this satellite, but foresight is sometimes difficult to achieve.

Advanced Materials, EarlyView.Self‐invalidating multilayer physical unclonable functions (PUFs) integrate fingerprint‐like metal nanopattern bilayers from block copolymer templates with highly reactive reduced graphene oxide (rGO) interlayers. This tamper‐responsive architecture blocks all unauthorized physical and chemical replication attempts while autonomously deactivating ...
