We are working on the synthesis and characterization of ceramic and single crystal materials with novel electronic and magnetic properties. Numerous complex oxide materials have been successfully crystallized by the Traveling Solvent Floating Zone (TSFZ) method using an optical furnace. This includes cuprates, manganates, orthoferrites, cobaltites, borates and phosphates. Novel chalcogenide iron superconductors have been synthesized as powders and single crystals (Bridgman method).

Tips and Tricks for the Crystal Growth of Inorganic Materials
We are happy to announce that the call for abstracts for the Workshop on Tips and tricks for the crystal growth of inorganic materials is now open. The workshop brings together experts from the Solid State Chemistry and Condensed Matter Physics communities in order to discuss the accomplished progress and perspectives for future developments in the synthesis and crystal growth of materials with novel and interesting physical properties. The event will take place at the Paul Scherrer Institut (PSI), Switzerland, 26th-27th of August 2024.
Doctoral thesis award 2022 for Igor Plokhikh
Doctoral thesis award of the Dr. Alfons Paulus Foundation at the University of Regensburg, Faculty of Chemistry and Pharmacy for Igor Plokhikh
On 14th of July 2022 Dr Igor Plokhikh (currently postdoc at SSCG, LMX PSI) has been awarded with the Doctoral thesis award of the Dr. Alfons Paulus Foundation at the University of Regensburg, Faculty of Chemistry and Pharmacy. He completed his doctoral studies at the group of Prof. Arno Pfitzner working on synthesis, crystal growth and characterization of crystal and magnetic structures of new magnetic Eu2+-containing compounds. This work resulted in discovery of over 10 new compounds, some of which exhibit complex magnetic phase diagrams.

Discovery of charge order above roomtemperature in the prototypical kagome superconductor La(Ru1−xFex)3Si2
The kagome lattice is an intriguing and rich platform for discovering, tuning and understanding the diverse phases of quantum matter, crucial for advancing modern and future electronics. Despite considerable efforts, accessing correlated phases at room temperature has been challenging.
Ferromagnetic quantum critical point protected by nonsymmorphic symmetry in a Kondo metal
Quantum critical points (QCPs), zero-temperature phase transitions, are win- dows to fundamental quantum-mechanical phenomena associated with universal behaviour. Magnetic QCPs have been extensively investigated in the vicinity of antiferromagnetic order. However, QCPs are rare in metallic ferromagnets due to the coupling of the order parameter to electronic soft modes. Recently, antisymmetric spin-orbit coupling in noncentrosymmetric systems was suggested to protect ferromagnetic QCPs. Nonetheless, multiple centrosymmetric materials ...
Flat-band hybridization between f and d states near the Fermi energy of SmCoIn5
We present high-quality angle-resolved photoemission (ARPES) and density functional theory calculations (DFT+U) of SmCoIn5. We find broad agreement with previously published studies of LaCoIn5 and CeCoIn5, confirming that the Sm 4f electrons are mostly localized. Nevertheless, our model is consistent with an additional delocalized Sm component, stemming from hybridization between the 4f electrons and the metallic bands at “hot spot” positions in the Brillouin zone.
