International Conference on Superconductivity and Magnetism (ICSM) is one of the biggest conferences in the field of superconductors. This year it was held in Fethiye, Turkey on May 4-11, 2023 and it gathered over 500 participants from all around the world, including 22 scientists from Poland.

Dr. Shiv J. Singh from our Institute was invited to give a talk on “High-Pressure Growth and Physical Properties of Iron-Based Superconductors: 1111 and 1144”. He presented his team’s current results and highlighted the importance of the high-pressure growth effect on Iron-Based Superconductors with respect to Convenient Growth Methods at ambient pressure. Also our two Ph.D. students: Manasa Manasa, and Mohammad Azam, have presented their poster contributions. More information can be found on the conference website (https://icsm2023.org/).

One of the important subjects discussed at ICSM2023 was the recent report of superconductivity at room temperature in a N-doped lutetium hydride. This material was reported by the American group to show the superconducting properties at 20°C (10 kbar), (Nature 615, 244 (2023)). In this conference, Japanese and Chinese groups presented their studies on N-doped lutetium hydride under applied pressure. Unfortunately, both groups did not observe the superconducting behaviors even at very high pressures. Interestingly, in 2020 the same American group had reported room-temperature superconductivity in a carbonaceous sulfur hydride at about 15°C (Nature, 586, 373 (2020)) but the article was retracted after two years.
