MuSR search for fluctuating loop currents in cuprates
The origin of a mysterious pseudogap region in high-Tc superconductors is a challenging issue. It was proposed that the pseudogap is caused by a circulating-current order... -
Paramagnetic excitations in the topological Weyl semimetal Co3Sn2S2
In a magnetic Weyl semimetal (WSM) with broken time-reversal symmetry, large intrinsic anomalous Hall effect is expected if the Weyl nodes are close to Fermi energy, which... -
Anti-ferromagnetic ordering in the super-oxygenated (La,Sr)2CuO4+y supercondu...
We have obtained a LSCOO x = 0.06 single crystal where neutron diffraction shows field induced anti-ferromagnetic order with an onset field in the range 0-1T and increasing... -
µSR studies of the superconducting and magnetic properties of FeSe1-xSx
FeSe1-xSx is an important model system for investigating the relationship between superconductivity and nematicity. The nematicity can be suppressed systematically by the... -
Probing superconductivity, static magnetism and light ion diffusion in molecu...
In 2012 we demonstrated that molecular spacer layers could be intercalated in between FeSe layers resulting in a dramatic enhancement of the critical temperature: FeSe is itself... -
Magnetism in RT2Zn20: below and beyond the Stoner limit
Spontaneous ferromagnetism occurs when exceeding the "Stoner limit", a condition requiring the potential (Coulomb) energy to exceed the kinetic energy cost of splitting the... -
