Today's world, rapidly changing because of "big data", is encapsulated in trillions of tiny magnetic objects - magnetic bits - each of which stores one bit of data in magnetic disk drives. A group of scientists from the Max ...
Today almost all information stored on hard disc drives or cloud servers is recorded in magnetic media, because it is non-volatile (i.e. it retains the information when power is switched off) and cheap. For portable devices ...
Racetrack memory is a potential next-generation solution for our digital storage devices. However, current experiments using single-layer ferromagnetic nanowires are less efficient than expected. New research published in ...
Queen's University Belfast researchers have discovered a new way to create extremely thin electrically conducting sheets, which could revolutionise the tiny electronic devices that control everything from smart phones to ...
Physicists achieved a robust and reliable magnetization switching process by domain wall displacement without any applied fields. The effect is observed in tiny asymmetric permalloy rings and may pave the way to extremely ...
From compasses used in ancient overseas navigation to electrical motors, sensors, and actuators in cars, magnetic materials have been a mainstay throughout human history. In addition, almost all information that exists in ...
Magnets are not everywhere equally magnetized, but automatically split up into smaller areas, so-called magnetic domains. The walls between the domains are of particular importance: they determine the magnetic properties ...
Researchers at the Paul Scherrer Institute PSI have found a way of looking inside the iron core of transformers. Transformers are indispensable in regulating electricity both in industry and in domestic households. The better ...
New research from the Universities of Glasgow and Leeds could be an important step towards creating faster, higher-capacity, lower-power data storage.
Magnetic nanostructures – or rather: the interaction between charge, spin and current flow as a function of a temperature gradient in such structures – this is what the fast growing research area named "spin caloritronics" ...
