2Tuning 2D magnetism in Fe_(3+X)GeTe_(2) films by element doping显示文摘Two-dimensional(2D)ferromagnetic materials have been discovered with tunable magnetism and orbital-driven nodal-line features.Controlling the 2D magnetism in exfoliated nanoflakes via electric/magnetic fields enables a boosted Curie temperature(T_(C))or phase transitions.One of the challenges,however,is the realization of high T_(C) 2D magnets that are tunable,robust and suitable for large scale fabrication.Here,we report molecular-beam epitaxy growth of wafer-scale Fe_(3+X)GeTe_(2) films with T_(C) above room temperature.By controlling the Fe composition in Fe_(3+X)GeTe_(2),a continuously modulated T_(C) in a broad range of 185–320 K has been achieved.This widely tunable TC is attributed to the doped interlayer Fe that provides a 40%enhancement around the optimal composition X=2.We further fabricated magnetic tunneling junction device arrays that exhibit clear tunneling signals.Our results show an effective and reliable approach,i.e.element doping,to producing robust and tunable ferromagnetism beyond room temperature in a large-scale 2D Fe_(3+X)GeTe_(2) fashion.Shanshan Liu Zihan Li Ke Yang Enze Zhang Awadhesh Narayan Xiaoqian Zhang Jiayi Zhu Wenqing Liu Zhiming Liao Masaki Kudo Takaaki Toriyama Yunkun Yang Qiang Li Linfeng Ai Ce Huang Jiabao Sun Xiaojiao Guo Wenzhong Bao Qingsong Deng Yanhui Chen Lifeng Yin Jian Shen Xiaodong Han Syo Matsumura Jin Zou Yongbing Xu Xiaodong Xu Hua Wu Faxian Xiu 2022National Science Review2022,9,6:0
3Linux Kernel Data Races in Recent 5 Years显示文摘Data races are increasingly seen as concurrency bugs and they are difficult to reproduce and diagnose in parallel programs. Linux kernel is a large-scale software system, in which intensive thread-level parallelism and non-deterministic thread interleaving are more prone to race conditions. This paper conducts an investigation of real Linux kernel data races in recent 5 years. Our results show that there are about 500 real kernel data races reported and fixed in recent 5 years. File systems and drivers among all modules hold a much higher percentage of race conditions than other modules. We also conduct a case-bycase study on data races and graphically show how these data races are triggered with specific thread interleaving.Our analysis results are of interest to researchers and engineers who are committed to kernel data race detection and kernel development.SHI Jianjun JI Weixing WANG Yizhuo HUANG Lifu GUO Yunkun SHI Feng 2018Chinese Journal of Electronics2018,27,3:0
