Material Made Under High Pressure BaCoO3 Impersonates a Superconductor

Researchers report that a material (hexagonal HP-BaCoO3) made under high-pressure (6 GPa, 1200 °C) and was tested at ambient-pressure. The material (with a 2H crystal structure) has a short intrachain Co–Co distance of about 2.07 Å. The magnetization investigation revealed robust diamagnetic behavior below approximately 130 K when the material was exposed to weak applied magnetic fields (10 Oe) and a distinct “half-levitation” phenomenon below that temperature, as is often observed for superconductors. Its field-dependent magnetization profile, however, unveils the characteristics of ferromagnetism, marked by a substantial magnetic retentivity of 0.22(1) μB/Co at a temperature of 2 K. Electrical resistivity measurements indicate that HP-BaCoO3 is a ferromagnetic insulator, not a superconductor.

The material had what looked like superconductor characteristics but it was not a superconductor.

The research was in the Journal of the American Chemical Society. The researchers were from Princeton and Michigan State.

  1. In light of the LK99 developments, we can anticipate that more research on materials with unique and unexpected properties, like hexagonal HP-BaCoO3, will be conducted and reported. The incident has drawn attention to the importance of exploring novel materials and understanding their characteristics thoroughly.

    I feel the increased awareness and curiosity within the scientific community may lead to the discovery of more materials with intriguing properties. This is just the start.

  2. For all those that dissed the first novel non-superconducting prototype LK 99, this is what happens when you uncover a novel new class of materials. The experiments will continue and hopefully something useful will come of it.
