Ofer Kfir,Patrik Grychtol,Emrah Turgut,Ronny Knut,Ronny Knut,Dmitriy Zusin,Dimitar Popmintchev,Tenio Popmintchev,Hans T. Nembach,Hans T. Nembach,Justin M. Shaw,Avner Fleischer,Henry C. Kapteyn,Margaret M. Murnane,Oren Cohen +14 more
TL;DR: In this article, the first bright, phase-matched, extreme ultraviolet circularly-polarized high harmonics source was demonstrated for magnetic circular dichroism measurements at the M-shell absorption edges of Co.
Journal ArticleDOI
High Dynamic Range Pixel Array Detector for Scanning Transmission Electron Microscopy
Mark W. Tate,Prafull Purohit,Darol Chamberlain,Kayla X. Nguyen,Robert Hovden,Celesta S. Chang,Pratiti Deb,Emrah Turgut,John T. Heron,Darrell G. Schlom,Daniel C. Ralph,Gregory D. Fuchs,Katherine S. Shanks,Hugh T. Philipp,David A. Muller,Sol M. Gruner +15 more
TL;DR: In this paper, a hybrid pixel array detector (EMPAD) is proposed for use in electron microscope applications, especially as a universal detector for scanning transmission electron microscopy, which consists of a 500 µm thick silicon diode array bump-bonded pixel-by-pixel to an application specific integrated circuit.
Journal ArticleDOI
Ultrafast magnetization enhancement in metallic multilayers driven by superdiffusive spin current
Dennis Rudolf,Chan La-o-vorakiat,Marco Battiato,Roman Adam,Justin M. Shaw,Emrah Turgut,Pablo Maldonado,Stefan Mathias,Stefan Mathias,Patrik Grychtol,Hans T. Nembach,Thomas J. Silva,Martin Aeschlimann,Henry C. Kapteyn,Margaret M. Murnane,Claus M. Schneider,Peter M. Oppeneer +16 more
TL;DR: In this paper, the spin dynamics in magnetic trilayers can be driven by ultrafast light pulses, resulting in transient magnetization changes on femtosecond timescales.

Ultrafast Magnetization Enhancement in Metallic Multilayers Driven by Superdiffusive Spin Current
Emrah Turgut,Chan La-o-vorakiat,Patrik Grychtol,Henry C. Kapteyn,Margaret M. Murnane,Dennis Rudolf,Roman Adam,Claus M. Schneider,Marco Battiato,Pablo Maldonado,Peter M. Oppeneer,Stefan Mathias,Martin Aeschlimann,Justin M. Shaw,Hans T. Nembach,Thomas J. Silva +15 more
TL;DR: Spatially separate the spin dynamics using Ni/Ru/Fe magnetic trilayers and surprisingly find that optically induced demagnetization of the Ni layer transiently enhances the magnetizations of the Fe layer when the two layer magnetizations are initially aligned parallel.
Journal ArticleDOI
Controlling the Competition between Optically Induced Ultrafast Spin-Flip Scattering and Spin Transport in Magnetic Multilayers
Emrah Turgut,Chan La-o-vorakiat,Justin M. Shaw,Patrik Grychtol,Hans T. Nembach,Dennis Rudolf,Roman Adam,Martin Aeschlimann,Claus M. Schneider,Thomas J. Silva,Margaret M. Murnane,Henry C. Kapteyn,Stefan Mathias,Stefan Mathias +13 more
TL;DR: This work uses multilayers of Fe and Ni with different metals and insulators as the spacer material to conclusively show that spin currents can have a significant contribution to optically induced magnetization dynamics, in addition to spin-flip scattering processes.
