Shock-waves and commutation speed of memristors

Shao Tang, Federico Tesler, Fernando Gomez Marlasca +3

Progress of silicon based technology is nearing its physical limit, as minimum feature size of components is reaching a mere 10 nm. The resistive switching behaviour of transition…

Tuning the magnetic exchange via a control of orbital hybridization in Cr2(Te1-xWx)O6

M. Zhu, D. Do, C. R. Dela Cruz +4

We report the complex magnetic phase diagram and electronic structure of Cr2(Te1-xWx)O6 systems. While compounds with different x values possess the same crystal structure, they di…

Visualizing Skin Effects in Conductors with MRI: Li MRI Experiments and Calculations

Andrew J. Ilott, S. Chandrashekar, Andreas Klöckner +5

While experiments on metals have been performed since the early days of NMR (and DNP), the use of bulk metal is normally avoided. Instead, often powders have been used in combinati…
