Journal ArticleDOI
Magnetic bubblecade memory based on chiral domain walls
Kyoung-Woong Moon,Duck-Ho Kim,Sang-Cheol Yoo,Soong-Geun Je,Byong Sun Chun,Wondong Kim,Byoung-Chul Min,Chanyong Hwang,Sug-Bong Choe +8 more
TL;DR: Unidirectional motion of magnetic domain walls is the key concept underlying next-generation domain-wall-mediated memory and logic devices.
Journal ArticleDOI
Skyrmion motion driven by oscillating magnetic field.
Kyoung-Woong Moon,Duck-Ho Kim,Soong-Geun Je,Byong Sun Chun,Wondong Kim,Ziqiang Qiu,Sug-Bong Choe,Chanyong Hwang +7 more
TL;DR: In this paper, the authors show that a skyrmion of a few tens of nanometres can also be driven by high-frequency field oscillations, but with a different direction of motion from the in-plane component of the tilted oscillating field.
Journal ArticleDOI
Probing one antiferromagnetic antiphase boundary and single magnetite domain using nanogap contacts.
Han-Chun Wu,Mohamed Abid,Mohamed Abid,Byong Sun Chun,Rafael Ramos,Oleg N. Mryasov,Igor V. Shvets +6 more
TL;DR: It is argued that observations of a large magnetoresistance (MR), high resistivity, and a high saturation field are observed as compared with the case of probing a single Fe(3)O(4) domain are indicative of profound changes in the electronic transport across APBs.
Journal ArticleDOI
Control of skyrmion magnetic bubble gyration
TL;DR: In this article, the authors analytically derived both mass and spring constant terms, which are crucial parameters for describing the bubble gyration, and found the dependences of these two terms on several external parameters, including the bubble radius.
Journal ArticleDOI
Photo-enhanced gas sensing of SnS2 with nanoscale defects
Wenjie Yan,Dengyun Chen,Huei-Ru Fuh,Huei-Ru Fuh,Yinglan Li,Duan Zhang,Huajun Liu,Gang Wu,Lei Zhang,Xiang-Kui Ren,Jiung Cho,Miri Choi,Byong Sun Chun,Cormac Ó Coileáin,Hongjun Xu,Zhi Wang,Zhaotan Jiang,Ching-Ray Chang,Han-Chun Wu +18 more
TL;DR: In this article, a photo-enhanced NO2 gas sensor with a detection limit of 2.5 ppb was demonstrated, and the authors showed that S vacancies work as additional adsorption sites with fast adorption times and higher energy consumption compared with pristine SnS2.
