Hidden Density-Wave Instability in the Trimer Ruthenate BaRuO
Gang Cao, Hengdi Zhao, Adrienne Bond +9
We report a hidden density-wave instability in the trimer-based ruthenate Ba4Ru3O10, previously regarded as a pure antiferromagnet with a phase transition at TA=100 K. This transit…
Emergent Inductance from Chiral Orbital Currents in a Bulk Ferrimagnet
Gang Cao, Hengdi Zhao, Yu Zhang +10
We report the discovery of a new form of inductance in the bulk ferrimagnet Mn3Si2Te6, which features strong spin-orbit coupling, large magnetic anisotropy, and pronounced magnetoe…
Current-sensitive Hall effect in a chiral-orbital-current state
Yu Zhang, Yifei Ni, Pedro Schlottmann +3
Chiral orbital currents (COC) underpin a novel colossal magnetoresistance (CMR) in ferrimagnetic Mn3Si2Te6 [1]. Here we report the Hall effect in the COC state which exhibits the f…
Magnetic Structure and Spin Fluctuations in Colossal Magnetoresistance Ferrimagnet Mn3Si2Te6
Feng Ye, Masaaki Matsuda, Zachary Morgan +4
The ferrimagnetic insulator Mn3Si2Te6, which features a Curie temperature Tc at 78 K and a delicate yet consequential magnetic frustration, exhibits colossal magnetoresistance (CMR…
Control of chiral orbital currents in a colossal magnetoresistance material
Yu Zhang, Yifei Ni, Hengdi Zhao +5
Colossal magnetoresistance (CMR) is an extraordinary enhancement of the electric conductivity in the presence of a magnetic field. It is conventionally associated with a field-indu…
Mechanical control of physical properties in the van der Waals ferromagnet Cr2Ge2Te6 via application of electric current
Hengdi Zhao, Yifei Ni, Bing Hu +6
Cr2Ge2Te6 is a van der Waals ferromagnet with a Curie temperature at 66 K. Here we report a swift change in the magnetic ground state upon application of small DC electric current,…
The power of flexible lattice in Ca3Ru2O7: Exquisite control of the electrical transport via anisotropic magnetostriction
Hengdi Zhao, Hao Zheng, Jasminka Terzic +5
Ca3Ru2O7 is a correlated and spin-orbit-coupled system with an extraordinary anisotropy. It is both interesting and unique largely because this material exhibits conflicting phenom…
Strange electrical transport: Colossal magnetoresistance via avoiding fully polarized magnetization in ferrimagnetic insulator Mn3Si2Te6
Yifei Ni, Hengdi Zhao, Yu Zhang +3
Colossal magnetoresistance is of great fundamental and technological significance and exists mostly in the manganites and a few other materials. Here we report colossal magnetoresi…
A Novel ground state in a new dimer iridate Ba13Ir6O30 with Ir6+(5d3) Ions
Hengdi Zhao, Feng Ye, Hao Zheng +5
We have synthesized and studied a new iridate, Ba13Ir6O30, with unusual Ir oxidation states: 2/3 Ir6+(5d3) ions and 1/3 Ir5+(5d4) ions. Its crystal structure features dimers of fac…
Quantum liquid from strange frustration in the trimer magnet Ba4Ir3O10
Gang Cao, Hao Zheng, Hengdi Zhao +9
Quantum spin systems such as magnetic insulators usually show classical magnetic order, but such classical states can give way to quantum liquids with exotic entanglement through t…
Observation of a pressure-induced transition from interlayer ferromagnetism to intralayer antiferromagnetism in Sr4Ru3O10
H. Zheng, W. H. Song, J. Terzic +6
Sr4Ru3O10 is a Ruddlesden-Popper compound with triple Ru-O perovskite layers separated by Sr-O alkali layers. This compound presents a rare coexistence of interlayer (c-axis) ferro…
Decoupling of magnetism and electric transport in single-crystal (Sr1-xAx)2IrO4 (A = Ca or Ba)
H. D. Zhao, J. Terzic, H. Zheng +5
We report a systematical structural, transport and magnetic study of Ca or Ba doped Sr2IrO4single crystals. Isoelectronically substituting Ca2+ (up to 15%) or Ba2+ (up to 4%) ion f…
