Antiferromagnetic order and magnetic polarons in lightly doped LiCoO (x 0.9)
Sudip Pal, Pampa Sadhukhan, Waqar Suleman +2
We investigate the magnetic properties of LiCoO (x0.9) using bulk magnetization, specific heat, nuclear magnetic resonance (NMR) and electron paramagnetic resonance (…
Emergence of a Fluctuating Ground State in Y-kapellasite under Pressure
Dipranjan Chatterjee, Petr Doležal, Federico Abbruciati +17
Y-kapellasite (YCu(OH)Cl), which hosts an original anisotropic kagome sublattice, is a promising candidate for studying elusive and complex correlated physics. I…
Mott Intermittency at the Metal-Insulator Boundary
Yuxin Wang, Vladimir DobrosavljeviÄ, Jan JaroszyÅski +5
The resistivity maximum at a temperature is a recurring feature of bandwidth-tuned Mott systems, yet its meaning remains controversial: is it a coherence-incoh…
Quasiparticle to local moment crossover in bad metals
A. Chen, F. B. Kugler, P. Doležal +4
Non-Fermi-liquid charge transport in the vicinity of electronic instabilities has been intensely studied for decades. Deviations from in bad and strange met…
-type RuTiHfSi full-Heusler bulk thermoelectrics with
Fabian Garmroudi, Illia Serhiienko, Michael Parzer +4
Heusler compounds have emerged as important thermoelectric materials due to their combination of promising electronic transport properties, mechanical robustness and chemical stabi…
Universal relation between residual resistivity and A coefficient in correlated metals
Anna Yu. Efimova, Yohei Saito, Atsushi Kawamoto +3
The effects of strong electronic correlations and disorder are crucial for emergent phenomena such as unconventional superconductivity, metal-insulator transitions, and quantum cri…
