Spintronics

Spintronics is an emerging technology exploiting both the intrinsic spin of the electron and its associated magnetic moment, in addition to its fundamental electronic charge, in solid-state devices. Spintronics differs from the older magnetoelectronics, in that the spins are not only manipulated by magnetic fields, but also by electrical fields. Spintronics emerged from discoveries in

Shellshock Bash Vulnerability

Circuit design software list

What is the best free or cheap electronics design software? It is hard to say in this ever changing field. I some time ago mentioned some software examples in Top Free Electronics Design Tools posting and you can find a long comparison list at Wikipedia Comparison of EDA software page. For the circuit design I would
