Phys.org  July 1. 2024 A nickel-cobalt-manganese-indium magnetic shape-memory alloy, can be deformed and then returned to its original shape by driving it through a phase transition. When subjected to a magnetic field, the material undergoes a magnetic and structural phase transition, during which it absorbs and releases heat. An international team of researchers (USA – Oak Ridge National Laboratory, Texas A&M University, NIST, Russia) showed that localized magnon-phonon hybrid modes, which are inherently spread across reciprocal space, act as a bridge between phonons and magnons and result in substantial magnetic field–induced shifts in the phonons and alter phase stability. They […]
