Ferrofluid—an extraordinary magnetic liquid—reacts in mesmerizing ways when exposed to a powerful magnet. This visual experiment reveals the strange and fascinating behavior of magnetic fields in ...

A material’s response to an applied magnetic field can be characterized as diamagnetic, paramagnetic, ferromagnetic or antiferromagnetic. This study presents a diagnostic pen with ferrofluid ink ...

The authors use nitrogen-vacancy centre magnetometry to explore layer number and magnetic field evolution of ferromagnetic and antiferromagnetic domains in the A-type antiferromagnet CrPS 4.
