Researchers from Quingdou University of Science and Technology in China developed a method to produce “supermagnets” that could one day be used as targeted drug delivery vehicles. The team’s work was published in Physics Letters A.
Some magnetic materials are small enough that their magnetization randomly flips according to temperature; when scientists apply a magnetic field to these crystals, the material becomes almost as strongly magnetic as an ordinary fridge magnet. This type of magnetism, called superparamagnetism, is the strongest known type of magne
