Groundbreaking Discovery: Visualizing Zero-Field Pair Density Wave for the First Time
Researchers have made a breakthrough in the field of superconductivity by directly visualizing a pair density wave (PDW) in an iron-based superconductor without the presence of a magnetic field. This discovery challenges previous understandings of superconductivity and opens up new potential avenues for research. The material studied, EuRbFe4As4 (Eu-1144), naturally exhibits both superconductivity and ferromagnetism, providing a unique opportunity to investigate the connection between the two phenomena. The findings could contribute to the development of room-temperature superconductors and have implications for various applications.
