Study reveals unprecedented control of ferromagnetic behavior in 2D material. The scientists found that a 2D van der Waals crystal, part of a class of material whose atomically thin layers can be peeled off one by one with adhesive tape, possessed an intrinsic ferromagnetism.The discovery could have major implications for a wide range of applications that rely upon ferromagnetic materials, such as nanoscale memory, spintronic devices, and magnetic sensors...

The ability to control the motion of soft robots, coupled with flexibility, gives them potential applications ranging from biomedical technologies to manufacturing processes. Researchers are interested in using magnetic fields to control the movement of these soft robots because it can be done remotely – the control can be exerted without physically connecting to the polymer – and because magnetic fields are easily obtained from permanent magnets and electromagnets.

A team of researchers has now found a way of embedding long chains of nanoscale magnetite particles in sheets of elastic polymer to form a magnetic polymer nanoco...
