A Strain‐Mediated Magnetoelectric‐Spin‐Torque Hybrid Structure

Tianxiang Nan, Jia‐Mian Hu, Minyi Dai, Satoru Emori, more

Advanced Functional Materials > 29 > 6 > n/a - n/a

Magnetization dynamics induced by spin–orbit torques in a heavy‐metal/ferromagnet can potentially be used to design low‐power spintronics and logic devices. Recent computations have suggested that a strain‐mediated spin–orbit torque (SOT) switching in magnetoelectric (ME) heterostructures is fast, energy‐efficient, and permits a deterministic 180° magnetization switching. However, its experimental...

PalZ > 2016 > 90 > 2 > 377-387

Fossil Ginkgophyta are one of the most widely used indicators for estimating the paleoatmospheric CO₂ levels from the Triassic to present day. There are quite a few CO₂ estimates for the Triassic to Jurassic interval; however, the data from China are still limited. In this study, two fossil Ginkgoites species, Ginkgoites magnifolius Du Toit and Ginkgoites obrutschewii (Seward) Seward, are described...

IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society > 3326 - 3329

IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society

Chip-scale thermoelectric energy harvester designs based on Bi2Te3 are presented with a focus on improving power density per device area for applications exchanging heat with ambient air through a heat sink. Practical vacuum capping is found to be beneficial for improving energy density despite the additional shunt created by the bonding ring around the 10mm2 harvester chip. Optimized device performance...
