Transversal magneto-resistance in epitaxial Fe3O4 and Fe3O4/NiO exchange biased system

We have investigated transversal magneto-resistance (MR) in epitaxial Fe3O4 and Fe3O4/NiO exchange biased systems. It was found that the magnetic field dependence and the magnitude of the transversal MR in both systems strongly depend on the bias current d ...

Magnetic states of an individual Ni nanotube probed by anisotropic magnetoresistance

Anna Fontcuberta i Morral, Dirk Grundler, Daniel Rüffer, Martin Heiss, Eleonora Russo

Defined magnetization states in magnetic nanotubes could be the basic building blocks for future memory elements. To date, it has been extremely challenging to measure the magnetic states at the single-nanotube level. We investigate the magnetization state ...

Experimental observation of an enhanced anisotropic magnetoresistance in non-local configuration

We compare non-local magnetoresistance measurements in multi-terminal Ni nanostructures with corresponding local experiments. In both configurations, the measured voltages show the characteristic features of anisotropic magnetoresistance (AMR). However, th ...

Motion and tilt aftereffects occur largely in retinal, not in object coordinates

Michael Herzog, Marco Boi

A variety of aftereffects was found to be processed non-retinotopically. Other studies failed to ﬁnd non-retinotopic aftereffects. These experiments relied on paradigms involving eye movements. We have developed a paradigm, based on the Ternus–Pikler displ ...

Magnetotransport and Trapping of Magnetic Domain Walls in Spin Valves With Nanoconstrictions

Santiago Serrano Guisan

In a magnetic nanowire, a magnetic domain wall (DW) can move along the wire when an applied magnetic field or a spin-polarized current is applied. A magnetic spin-valve device composed of two nanowires connected by a nanosized constriction was prepared, on ...

Evaluating and Repairing Write Performance on Flash Devices

Anastasia Ailamaki, Frederick Ryan Johnson, Manoussos Gavriil Athanassoulis, Radu Ioan Stoica

In the last few years NAND flash storage has become more and more popular as price per GB and capacity both improve at exponential rates. Flash memory offers significant benefits compared to magnetic hard disk drives (HDDs) and DBMSs are highly likely to u ...

The complexity of reliable distributed storage

Ron Levy

Distributed storage systems based on commodity hardware have gained in popularity because they are cheaper, can be made more reliable and offer better scalability than centralized storage systems. However, implementing and managing such systems is more com ...

Abstractions for asynchronous distributed computing with malicious players

Marko Vukolic

In modern distributed systems, failures are the norm rather than the exception. In many cases, these failures are not benign. Settings such as the Internet might incur malicious (also called Byzantine or arbitrary) behavior and asynchrony. As a result, and ...

How Fast Can a Very Robust Read Be?

Rachid Guerraoui, Marko Vukolic

This paper studies the time complexity of reading unauthenticated data from a distributed storage made of a set of failure-prone base objects. More specifically, we consider the abstraction of a robust read/write storage that provides wait-free access to u ...
