Revealing a charge-density-wave gap in the predicted weak topological insulator HoSbTe
J. L. Liu, R. Liu, M. Yang +7
HoSbTe was predicted to be a weak topological insulator, whose spin-orbit coupling (SOC) gaps are reported to be as large as hundreds of meV. Utilizing infrared spectroscopy, we fi…
Spin fluctuation induced Weyl semimetal state in the paramagnetic phase of EuCdAs
J. -Z. Ma, S. M. Nie, C. J. Yi +22
Weyl fermions as emergent quasiparticles can arise in Weyl semimetals (WSMs) in which the energy bands are nondegenerate, resulting from inversion or time-reversal symmetry breakin…
Observation of multiple types of topological fermions in PdBiSe
B. Q. Lv, Z. -L. Feng, J. -Z. Zhao +12
Topological semimetals with different types of band crossings provide a rich platform to realize novel fermionic excitations, known as topological fermions. In particular, some fer…
Magnetic competition induced colossal magnetoresistance in n-type HgCr2Se4 under high pressures
J. P. Sun, Y. Y. Jiao, C. J. Yi +7
The n-type HgCr2Se4 exhibits a sharp semiconductor-to-metal transition (SMT) in resistivity accompanying the ferromagnetic order at TC = 106 K. Here, we investigate the effects of…
Evidence for ground state and defect-induced spin glass behaviour in the pyrochlore osmate YOsO
N. R. Davies, C. V. Topping, H. Jacobsen +14
We present AC and DC magnetometry, heat capacity, muon spin relaxation (SR) and resonant inelastic X-ray scattering (RIXS) studies of the pyrochlore osmate YOsO. We…
Crossover from itinerant to localized magnetic excitations through the metal-insulator transition in NaOsO
J. G. Vale, S. Calder, C. Donnerer +8
NaOsO undergoes a metal-insulator transition (MIT) at 410 K, concomitant with the onset of antiferromagnetic order. The excitation spectra have been investigated throu…
