Coexisting Z-type charge and bond order in metallic NaRuO
Arvind Kumar Yogi, Alexander Yaresko, C. I. Sathish +7
How particular bonds form in quantum materials has been a long-standing puzzle. Two key concepts dealing with charge degrees of freedom are dimerization (forming metal-metal bonds)…
Pressure-induced transition from Jeff=1/2 to S=1/2 states in CuAl2O4
Hwanbeom Cho, Choong H. Kim, Yongmoon Lee +12
The spin-orbit entangled (SOE) Jeff-state has been a fertile ground to study novel quantum phenomena. Contrary to the conventional weakly correlated Jeff=1/2 state of 4d and 5d tra…
Sizeable suppression of thermal Hall effect upon isotopic substitution in strontium titanate
Sangwoo Sim, Heejun Yang, Ha-Leem Kim +4
We report measurements of the thermal Hall effect in single crystals of both pristine and isotopically substituted strontium titanate. We discovered a two orders of magnitude diffe…
Symmetry breaking and unconventional charge ordering in single crystal NaRuO
Arvind Yogi, C. I. Sathish, Hasung Sim +3
The interplay of charge, spin, and lattice degrees of freedom in matter leads to various forms of ordered states through phase transitions. An important subclass of these phenomena…
Spin-Wave Spectrum in `Single-Domain' Magnetic Ground State of Triangular Lattice Antiferromagnet CuFeO2
Taro Nakajima, Setsuo Mitsuda, Tendai Haku +6
By means of neutron scattering measurements, we have investigated spin-wave excitation in a collinear four-sublattice (4SL) magnetic ground state of a triangular lattice antiferrom…
Pressure-induced commensurate magnetic order in multiferroic
Hiroyuki Kimura, Keisuke Nishihata, Yukio Noda +4
The pressure () -- temperature () phase diagram for microscopic magnetism in the multiferroic compound HoMnO was established using neutron diffraction measurement…
Low-Temperature Structure of the Quarter-Filled Ladder Compound alpha'-NaV2O5
Hiroshi Sawa, Emi Ninomiya, Tetsuo Ohama +7
The low-temperature (LT) superstructure of -NaVO was determined by synchrotron radiation x-ray diffraction. Below the phase transition temperature associated with atomi…
