Ronny J. Knut, Erna Delczeg-Czirjak, Somnath Jana, Justin M. Shaw, Hans T. Nembach, Yaroslav Kvashnin, Robert Stefaniuk, Rameez Malik, Patrik Grychtol, Dmitriy Zusin, Christian Gentry, Raghuveer Chimata, Manuel Pereiro, Johan Soderstrom, Emrah Turgut, Martina Ahlberg, Johan Akerman, H C. Kapteyn, Margaret M. Murnane, Dario A. Arena, Olle Eriksson, Olof Karis, Thomas J. Silva
Ni 0.8Fe 0.2 (Py) and Py alloyed with Cu exhibit intriguing ultrafast demagnetization behavior, where the Ni magnetic moment shows a delayed response relative to the Fe, an effect which is strongly enhanced by Cu alloying. We have studied a broad range of

Particle tracking of microelectromechanical system performance and reliability

October 25, 2018
Author(s)
Craig R. Copeland, Craig D. McGray, Jon C. Geist, Samuel M. Stavis
Microelectromechanical systems (MEMS) that require contact of moving parts to implement complex functions have demonstrated critical limits of performance and reliability. Here, we advance a particle tracking method to measure MEMS motion in operando at

Suppression of Antiferromagnetic Spin Fluctuations in Superconducting Cr 0.8 Ru 0.2

October 25, 2018
