Magnets often harbour hidden beauty. Take a simple fridge magnet: Somewhat counterintuitively, it is 'sticky' on one side but not the other. The secret lies in the way the magnetisation is arranged in ...

This could explain why some black holes are able to grow to millions or billions of times the mass of our sun. When you purchase through links on our site, we may earn an affiliate commission. Here’s ...

Magnetometry exploiting color center defects in diamond probes and magneto-optic imaging have been found to complement each other. This supports progress towards the creation of more effective data ...

Ferromagnetic materials have a self-generating magnetic field, ferroelectric materials generate their own electrical field. Although electric and magnetic fields are related, physics tells us that ...

Recently, observation of new topological magnetic structures represented by skyrmions is expected to provide new paths in constructing spintronic devices. In magnetic bubbles, although these are ...

Controlling this state paves the way for the creation of more intelligent, reconfigurable and energy-efficient devices that mimic the brain. The use of Big Data has multiplied the energy demand in ...

Analyzing magnetic nanostructures with a high resolution is a test-and-measurement challenge, but it’s important for both advanced physics insight as well as real-world products such as high-density ...

NASA scientists spotted a strange polar vortex near the Sun's northern pole. The vortex appears to be part of a huge filament of solar plasma that the space agency says broke away from the Sun's ...
