Bradley N. Engel,Johan Åkerman,Brian R. Butcher,Renu W. Dave,Mark F. Deherrera,Mark A. Durlam,Gregory W. Grynkewich,Jason Allen Janesky,Srinivas V. Pietambaram,N. D. Rizzo,J.M. Slaughter,Kenneth H. Smith,Jijun Sun,Saied N. Tehrani +13 more
TL;DR: In this paper, a 4Mb magnetoresistive random access memory (MRAM) with a novel magnetic bit cell and toggle switching mode is presented, which greatly improves the operational performance of the MRAM as compared to conventional MRAM.
Journal ArticleDOI
Toward a Universal Memory
TL;DR: The magnetoresistive random access memory (MRAM) as mentioned in this paper is a promising candidate for a universal memory that combines all the strengths and none of the weaknesses of the existing memory types.
Journal ArticleDOI

TL;DR: In this article, the potential of spintronics in four key areas of application (memory, sensors, microwave devices, and logic devices) is examined and the challenges that need to be addressed in order to integrate spintronic materials and functionalities into mainstream microelectronic platforms.
Journal ArticleDOI
Direct observation of a propagating spin wave induced by spin-transfer torque
Marco Madami,Stefano Bonetti,Giancarlo Consolo,Silvia Tacchi,Giovanni Carlotti,Gianluca Gubbiotti,Fred Mancoff,Mazher Ahmed Yar,Johan Åkerman,Johan Åkerman +9 more
TL;DR: This work directly observes a propagating spin wave launched from a spin torque oscillator with a nanoscale electrical contact into an extended Permalloy (nickel iron) film through the spin transfer torque effect, and shows that spin waves with tunable frequencies can propagate for several micrometres.
