Unusual UUDD magnetic chain structure of the spin-1/2 tetragonally distorted spinel GeCu2O4
T. Zou, Y. -Q. Cai, C. R. dela Cruz +4
GeCu2O4 exhibits a tetragonal spinel structure due to the strong Jahn-Teller distortion associated with Cu2+ ions. We show that its magnetic structure can be described as slabs com…
Cokrig-and-Regress for Spatially Misaligned Environmental Data
Z. Y. Tho, F. K. C. Hui, A. H. Welsh +1
Spatially misaligned data, where the response and covariates are observed at different spatial locations, commonly arise in many environmental studies. Much of the statistical lite…
Unusual interlayer quantum transport behavior caused by the zeroth Landau level in YbMnBi2
J. Y. Liu, J. Hu, D. Graf +10
Relativistic fermions in topological quantum materials are characterized by linear energy-momentum dispersion near band crossing points. Under magnetic field, relativistic fermions…
Magnetotransport Spectroscopy of Strongly Rashba-Split Hole Subbands Reveals Many-Body Interactions
F. Sfigakis, N. A. Cockton, M. Korkusinski +13
We report the results of magnetotransport experiments carried out on low-disorder 2D hole gases (2DHG) in the strongly correlated liquid regime, hosted in dopant-free (100) GaAs/Al…
Magnetic Field Induced Phase Transition in Spinel GeNi2O4
T. Basu, T. Zou, Z. Dun +7
Cubic spinel GeNi2O4 exhibits intriguing magnetic properties with two successive antiferromagnetic phase transitions (TN1 12.1 and TN2 11.4 K) with the absence of any structural tr…
Enhanced effective masses, spin-orbit polarization, and dispersion relations in 2D hole gases under strongly asymmetric confinement
N. A. Cockton, F. Sfigakis, M. Korkusinski +13
The dispersion of Rashba-split heavy-hole subbands in GaAs two-dimensional hole gases (2DHGs) is difficult to access experimentally because strong heavy-hole-light-hole mixing prod…
Magnetoelectric coupling in the paramagnetic state of a metal-organic framework
W. Wang, L. -Q. Yan, J. -Z. Cong +8
Although the magnetoelectric effects - the mutual control of electric polarization by magnetic fields and magnetism by electric fields, have been intensively studied in a large num…
Magnetic structure and magnetoelectric coupling in antiferromagnet Co5(TeO3)4Cl2
B. Yu, L. Huang, J. S. Li +16
The van der Waals (vdW) layered multiferroics, which host simultaneous ferroelectric and magnetic orders, have attracted attention not only for their potentials to be utilized in n…
Colossal magnetoresistance in a Mott insulator via magnetic field-driven insulator-metal transition
M. Zhu, J. Peng, T. Zou +6
We present a new type of colossal magnetoresistance (CMR) arising from an anomalous collapse of the Mott insulating state via a modest magnetic field in a bilayer ruthenate, Ti-dop…
Non-Fermi surface nesting driven commensurate magnetic ordering in Fe-doped SrRuO
M. Zhu, K. V. Shanavas, Y. Wang +11
SrRuO, an unconventional superconductor, is known to possess an incommensurate spin density wave instability driven by Fermi surface nesting. Here we report a static spin d…
