Novel quantum phase of the chromium spinel oxide HgCrO in high magnetic fields
Shojiro Kimura, Shusaku Imajo, Masaki Gen +4
In this study, we have performed the magnetocaloric effect and the specific heat measurements of chromium spinel oxide HgCrO, wherein the magnetic Cr ions form a hig…
Magnetic ordering with an XY-like anisotropy in the honeycomb lattice iridates ZnIrO and MgIrO synthesized via a metathesis reaction
Yuya Haraguchi, Chishiro Michioka, Hiroaki Ueda +3
We have successfully synthesized the novel antiferromagnets with Ir honeycomb lattice ZnIrO and MgIrO and investigated their magnetic and thermodynamic properties. T…
Quantum Interactions of Topological Solitons from Electrodynamics
Hirohiko Shimada, Kazutaka Takahashi, Hiroaki. T. Ueda
The Casimir energy for the classically stable configurations of the topological solitons in 2D quantum antiferromagnets is studied by performing the path-integral over quantum fluc…
Quantum solitons with emergent interactions in a model of cold atoms on the triangular lattice
Hiroaki T. Ueda, Yutaka Akagi, Nic Shannon
Cold atoms bring new opportunities to study quantum magnetism, and in particular, to simulate quantum magnets with symmetry greater than . Here we explore the topological ex…
Spin Jam: a quantum-fluctuation-induced glassy state of a frustrated magnet
Junjie Yang, Anjana Samarakoon, Sachith Dissanayake +8
Since the discovery of spin glasses in dilute magnetic systems, their study has been largely focused on understanding randomness and defects as the driving mechanism. The same para…
Structural anomalies and short-range magnetic correlations in the orbitally degenerated system SrVO
Ichihiro Yamauchi, Kazuhiro Nawa, Masatoshi Hiraishi +10
We report on the electronic ground state of a layered perovskite vanadium oxide SrVO studied by the combined use of synchrotron radiation x-ray diffraction (SR-XRD) and muo…
