Journal ArticleDOI
Unidirectional spin-torque driven magnetization dynamics
Joseph Sklenar,Joseph Sklenar,Wei Zhang,Wei Zhang,Matthias B. Jungfleisch,Hilal Saglam,Hilal Saglam,Scott Grudichak,Wanjun Jiang,Wanjun Jiang,John E. Pearson,John B Ketterson,Axel Hoffmann +12 more
TL;DR: In this paper, the authors demonstrate how spin-transfer torques in general result in unidirectional ferromagnetic resonance dynamics upon field reversal, which is a direct consequence of both field-like and damping-like dynamic torques simultaneously driving the motion.
Journal ArticleDOI
Fabrication of bismuth nanowires with a silver nanocrystal shadowmask
S. H. Choi,Kang L. Wang,Martin S. Leung,Gary W. Stupian,Nathan Presser,B. A. Morgan,R. E. Robertson,Margaret H. Abraham,E. E. King,M. B. Tueling,Sungwook Chung,James R. Heath,Sunglae Cho,John B Ketterson +13 more
TL;DR: In this paper, bismuth nanowires with low energy electron beam lithography using silver (Ag) nanocrystal shadowmasks and a subsequent chlorine reactive ion etching were fabricated.

Method and apparatus for monitoring and measuring the surface tension of a fluid using fiber optics
TL;DR: In this article, a noncontact method and apparatus for measuring and monitoring the surface of a fluid using fiber optics and interferometric detection to permit measurement mechanical characteristics' fluid surfaces is presented.
Journal ArticleDOI
Osteoblast proliferation on hydroxyapatite coated substrates prepared by right angle magnetron sputtering.
