> To further verify the superconducting properties, we conducted magnetic measurements on the sample, but unfortunately, no obvious Meissner signal was observed, indicating that the superconducting volume fraction of the sample may be very small. The preparation of high-purity samples are still a challenging task.
- klimt 3y agoThis is one of my key takeaways as well. It's a shame they didn't include their magnetization measurements, even if it didn't confirm superconductivity. The first conclusive paper will have to demonstrate a superconducting transition in both electrical resistivity and magnetization.
