Article published on magnetic phase transition in artificial square ice
Researchers from the Mesoscopic Systems and at the Paul Scherrer Institute have combined their expertise to extend the applicability of the fundamental concepts of continuous phase transitions to mesoscopic magnetic systems.
Combining synchrotron x-ray scattering and numerical simulations, it was established that the phase transition occurring in artificial square ice, a magnetic metamaterial consisting of a two-dimensional array of nanomagnets, belongs to the two-dimensional Ising universality class. These results extend to magnetic metamaterials the theoretical concepts established for phase transitions in conventional materials. The researchers published their results in the Physical Review B as an Editor’s suggestion.
