Raman Scattering Evidence for Fluctuating Kagome-Plane Moments in $B ∥ [111]$ in Pr $_{2}$ Zr $_{2}$ O $_{7}$ pyrochlore

Yuanyuan Xu, Huiyuan Man, Nan Tang +6

The exotic magnetic properties of the pyrochlore Pr $_{2}$ Zr $_{2}$ O $_{7}$ are determined by the coupling of spin, orbital, and lattice degrees of freedom. Magnetism in this material origi…

Electrical Regulation of Transverse Spin Currents in Unconventional Magnetic Ferroeletrics

Yudi Yang, Zhuang Qian, Ruichun Xiao +4

We identify hexagonal YMnO $_{3}$ as a material realization of the elusive $β$ -phase of unconventional magnetism, a noncollinear, noncoplanar antiferromagnetic state defined by intrin…

Probing scattering of Raman phonons on magnetic and electronic excitations in pyrochlores Nd $_{2}$ Zr $_{2}$ O $_{7}$ and Nd $_{2}$ Ir $_{2}$ O $_{7}$

Sami Muhammad, Yuanyuan Xu, Christos Kakogiannis +6

Magnetic rare earth atoms on pyrochlore lattice can produce such exotic magnetic states as spin ice and quantum spin ice. These states are a result of the frustration in the pyroch…

Comparative Raman Scattering Study of Crystal Field Excitations in Co-based Quantum Magnets

Banasree S. Mou, Xinshu Zhang, Li Xiang +8

Co-based materials have recently been explored due to potential to realise complex bond-dependent anisotropic magnetism. Prominent examples include Na $_{2}$ Co $_{2}$ TeO $_{6}$ , BaCo $_{2}$ (As…

Ramification of complex magnetism in Nd $_{2}$ Ir $_{2}$ O $_{7}$ observed by Raman scattering spectroscopy

Yuanyuan Xu, Yang Yang, Jérémie Teyssier +6

Using Raman scattering spectroscopy, we uncover a complex magnetic behavior of Nd $_{2}$ Ir $_{2}$ O $_{7}$ , which stands out among magnetic pyrochlores by the lowest temperature of the all-…

Weyl-Luttinger phase transition in pyrochlore iridates revealed by Raman scattering

Predrag Nikolić, Yuanyuan Xu, Takumi Ohtsuki +2

Pyrochlore iridates are thought to be a fertile ground for the realization of topologically non-trivial and strongly correlated states of matter. Here we provide a compelling evide…

Phonon spectrum of Pr $_{2}$ Zr $_{2}$ O $_{7}$ and Pr $_{2}$ Ir $_{2}$ O $_{7}$ as an evidence of coupling of the lattice with electronic and magnetic degrees of freedom

Yuanyuan Xu, Huiyuan Man, Nan Tang +5

Magnetic materials with pyrochlore crystal structure form exotic magnetic states due to the high lattice frustration. In this work we follow the effects of coupling of the lattice…

A magnetic continuum observed by terahertz spectroscopy in a quantum spin liquid candidate BaCo $_{2}$ (AsO $_{4}$ ) $_{2}$

Xinshu Zhang, Yuanyuan Xu, T. Halloran +5

Quantum spin liquids (QSLs) are topologically ordered exotic states of matter that host fractionalized excitations. Kitaev proposed a particular route towards a QSL via strongly bo…

Importance of dynamic lattice effects for crystal field excitations in quantum spin ice candidate Pr $_{2}$ Zr $_{2}$ O $_{7}$

Yuanyuan Xu, Huiyuan Man, Nan Tang +5

Pr $_{2}$ Zr $_{2}$ O $_{7}$ is a pyrochlore quantum spin-ice candidate. Using Raman scattering spectroscopy we probe crystal electric field excitations of Pr $^{3 +}$ , and demonstrate the impo…
