Instability Pattern Formation in a Liquid Metal under High Magnetic Fields

Abstract Magnetic field can generate interface instability when some liquids are put close to magnetic field. A well-known interface instability is called Rosensweig instability or normal field instability. Here we report that pure liquid Co can be highly undercooled close to its Curie temperature i...
