Journal ArticleDOI
Soft X-ray microscopy at a spatial resolution better than 15 nm
Weilun Chao,Weilun Chao,Bruce Harteneck,J. Alexander Liddle,Erik H. Anderson,David Attwood,David Attwood +6 more
TL;DR: The achievement of sub-15-nm spatial resolution with a soft X-ray microscope—and a clear path to below 10 nm—using an overlay technique for zone plate fabrication is reported.
Journal ArticleDOI
Nanofabrication and diffractive optics for high-resolution x-ray applications
Erik H. Anderson,Deirdre L. Olynick,Bruce Harteneck,Eugene Veklerov,Gregory Denbeaux,Weilun Chao,Angelic Lucero,Lewis Johnson,David Attwood +8 more
TL;DR: In this paper, a diffractive Fresnel zone plate lens was used for short wavelength x-ray radiation microscopy at the Advanced Light Source Synchrotron in Berkeley, California.
Journal ArticleDOI
Thermal generation, manipulation and detection of skyrmions
Zidong Wang,Minghua Guo,Hengan Zhou,Le Zhao,Teng Xu,Riccardo Tomasello,Hao Bai,Yiqing Dong,Soong-Geun Je,Weilun Chao,Hee-Sung Han,Suseok Lee,Ki-Suk Lee,Yunyan Yao,Wei Han,Cheng Song,Huaqiang Wu,Mario Carpentieri,Giovanni Finocchio,Mi-Young Im,Shi-Zeng Lin,Wanjun Jiang +21 more
TL;DR: In this article, the unidirectional diffusion of skyrmions from the hot region towards the cold region is experimentally observed, which can be theoretically explained by the combined contribution from repulsive forces and thermal spin-orbit torques in competing with magnonic spin torques and entropic forces.
Journal ArticleDOI
Magnetic soft x-ray microscopy at 15 nm resolution probing nanoscale local magnetic hysteresis "invited…
Dong-Hyun Kim,Peter Fischer,Weilun Chao,Erik H. Anderson,Mi-Young Im,Sung-Chul Shin,Sug-Bong Choe +6 more
TL;DR: In this article, the evolution of magnetic domain patterns in a nanogranular CoCrPt film with a pronounced perpendicular magnetic anisotropy was studied, and the authors were able to generate local magnetic hysteresis map on a nanometer scale.
Journal ArticleDOI
Soft x-ray microscopy to 25 nm with applications to biology and magnetic materials
Greg Denbeaux,Erik H. Anderson,Weilun Chao,Weilun Chao,T. Eimüller,Lewis Johnson,M. Köhler,Carolyn A. Larabell,Mark LeGros,Peer Fischer,A. Pearson,Gisela Schütz,Deborah Yager,David Attwood,David Attwood +14 more
TL;DR: In this paper, the magnetic domain structure is studied at high spatial resolution with X-ray magnetic circular dichroism (X-MCD) as a huge element-specific magnetic contrast mechanism, occurring e.g. at the L2,3 edges of transition metals.
