The article ‘Synergistic Doping and Stabilisation of Magnetically Tunable LnTi₃(Sb,Sn)₄ (Ln: Ce–Gd) Kagome Metals’ was published on 23 July 2026 in the Journal of the American Chemical Society (JACS), one of the most highly regarded scientific journals in the fields of chemistry and materials science. Karolina Górnicka, PhD, Eng., is one of the co-authors of the paper and is listed as affiliated with the Oak Ridge National Laboratory and the Gdańsk University of Technology.

The research was conducted by an interdisciplinary team of scientists from, among others, the Oak Ridge National Laboratory and the University of Central Florida. It focused on the synthesis and characterisation of new compounds belonging to the kagome metal group. The researchers demonstrated that by carefully selecting the chemical composition, it is possible to stabilise these new structures whilst simultaneously controlling their magnetic and electronic properties.

“This publication is an excellent example of just how important collaboration between specialists from different fields is in modern science. In this project, we combined the synthesis of new materials and their detailed characterisation with advanced theoretical computations and experiments to directly investigate the electronic structure of materials. It was only by bringing all these methods together that we were able to understand why the new compounds are stable and how their properties can be controlled,” explained Karolina Górnicka, PhD, Eng.

A new strategy for material design

The approach adopted by the team has been defined as ‘synergistic doping’. This could become a strategy for producing subsequent materials with desired and controllable physical properties.

“We have shown that by carefully selecting the chemical composition, it is possible not only to produce new chemical compounds, but also to modify their magnetic and electronic properties in a controlled manner. This paves the way for designing materials with desired properties that may, in the future, find applications in electronics, spintronics and quantum technologies. Our results also show that synergistic doping could become a universal strategy for discovering further materials with unique physical properties,” added the researcher.

Karolina Górnicka, PhD, Eng., is an assistant professor at the Faculty of Applied Physics and Mathematics at the Gdańsk University of Technology. She also has an academic affiliation with the Oak Ridge National Laboratory in the USA, one of the US Department of Energy’s largest research laboratories.
