Magnetic devices are components for creating, manipulating or detecting magnetic fields. This can include magnetic memories, magnetometers and devices for magneto-optics. Magnetism can also play a central role in spintronic devices.
The spintronics based complex network is promising for next generation computing systems but hampered by short-range spin-wave coupling. The authors make progress by achieving long range and tunable mutual synchronization of two spin-torque oscillators with improved emission power and signal linewidth.
Nanoscale magnetic devices play a key role in modern technologies but current applications involve only 2D structures like magnetic discs. Here the authors review recent progress in the fabrication and understanding of 3D magnetic nanostructures, enabling more diverse functionalities.
The injection, transport and manipulation of spins using electric fields in ultrathin films of black phosphorus show the potential of this material as a platform for two-dimensional semiconductor spintronics devices.
Broadband nitrogen–vacancy centre magnetometry demonstrates how commercial hard-disk write heads may become useful experimental tools for nanoscale applications involving magnetism and magnetic resonance.
