High‐Entropy Magnetism of Murunskite

Henrik Moodysson Rønnow, Ivica Zivkovic, Thomas La Grange, Davor Tolj, Rongrong Cai

Murunskite (K 2 FeCu 3 S 4 ) bridges the two known families of high‐temperature superconductors, cuprates and iron‐pnictides, structurally and electronically. Like these families, murunskite exhibits an antiferromagnetic (AF)‐like response with an ordered ...

Dynamic Jahn-Teller effect in the strong spin-orbit coupling regime

Henrik Moodysson Rønnow, Oleg Yazyev, Ivica Zivkovic, Jian Rui Soh, Ravi Yadav, Jana Pásztorová, Davor Tolj

Exotic quantum phases, arising from a complex interplay of charge, spin, lattice and orbital degrees of freedom, are of immense interest to a wide research community. A well-known example of such an entangled behavior is the Jahn-Teller effect, where the l ...

Interplay between disorder and electronic correlations in compositionally complex alloys

László Forró, Jan Hugo Dil, Luka Ciric, Edoardo Martino, Xavier François Mettan, Trpimir Ivsic, Davor Tolj

Owing to their exceptional mechanical, electronic, and phononic transport properties, compositionally complex alloys, including high-entropy alloys, represent an important class of materials. However, the interplay between chemical disorder and electronic ...

High-Temperature Phase Transitions Preceding the Decomposition of Mixed Valence Aluminum Titanate Pseudobrookite

Henrik Moodysson Rønnow, Arnaud Magrez, Ivica Zivkovic, Yong Liu, Davor Tolj

Dark blue single crystals of Al1.753+Ti1.04+Ti0.253+O5 were grown with a novel synthesis method based on the reaction of a Ti3+/Ti4+-containing langbeinite melt and porous alpha-alumina crucible. The obtained needles crystallize in the pseudobrookite struc ...

Spectroscopic signatures and origin of hidden order in Ba2MgReO6

Henrik Moodysson Rønnow, Oleg Yazyev, Ivica Zivkovic, Jana Pásztorová, Davor Tolj

Clarifying the underlying mechanisms that govern ordering transitions in condensed matter systems is crucial for comprehending emergent properties and phenomena. While transitions are often classified as electronically driven or lattice-driven, we present ...

Evidence for three-dimensional Dirac conical bands in TlBiSSe by optical and magneto-optical spectroscopy

Davor Tolj

TlBiSSe is a rare realization of a three-dimensional semimetal with a conically dispersing band that has an optical response which is well isolated from other contributions in a broad range of photon energies. We report optical and magneto-optical spectros ...

Synthesis of murunskite single crystals: A bridge between cuprates and pnictides

László Forró, Henrik Moodysson Rønnow, Ivica Zivkovic, Ana Akrap, Edoardo Martino, Konstantin Semeniuk, Trpimir Ivsic, Davor Tolj

Numerous contemporary investigations in condensed matter physics are devoted to high temperature (high-T-c) cuprate superconductors. Despite its unique effulgence among research subjects, the enigma of the high-T-c mechanism still persists. One way to adva ...
