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…
Interaction of Magnetic Fields with Spinons in a Fractionalized State
Yu Zhang, Hengdi Zhao, Tristan R. Cao +4
The 4d-electron trimer lattice exhibits either a quantum spin liquid (QSL) or a heavy-fermion strange metal (HFSM) phase, depending on Nb content. In the QSL state, itinerant spino…
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…
Transition between heavy-fermion strange metal and quantum spin liquid in a 4d-electron trimer lattice
Hengdi Zhao, Yu Zhang, Pedro Schlottmann +2
We present experimental evidence that a heavy Fermi surface consisting of itinerant, charge-neutral spinons underpins both heavy-fermion-strange-metal (without f electrons) and qua…
Structural changes induced by electric currents in a single crystal of PrCuO
Susmita Roy, Feng Ye, Zachary Morgan +7
We demonstrate a novel approach to the structural and electronic property modification of perovskites, focusing on PrCuO, an undoped parent compound of a class of electron-…
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…
Fortuitous partners of antiferromagnetic and Mott states in spin-orbit-coupled Sr2IrO4: A study of Sr2Ir1-xMxO4 (M=Fe or Co)
Bing Hu, Hengdi Zhao, Yu Zhang +3
Sr2IrO4 is an archetypal spin-orbit-coupled Mott insulator with an antiferromagnetic state below 240 K. Here we report results of our study on single crystals of Sr2Ir1-xFexO4 (0<x…
A Novel ground state in a new dimer iridate Ba13Ir6O30 with Ir6+(5d3) Ions

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
