Probing scattering of Raman phonons on magnetic and electronic excitations in pyrochlores NdZrO and NdIrO
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…
Ramification of complex magnetism in NdIrO observed by Raman scattering spectroscopy
Yuanyuan Xu, Yang Yang, Jérémie Teyssier +6
Using Raman scattering spectroscopy, we uncover a complex magnetic behavior of NdIrO , 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 thermal Hall effect in a metallic spin ice
Taiki Uehara, Takumi Ohtsuki, Masafumi Udagawa +2
It has become common knowledge that phonons can generate thermal Hall effect in a wide variety of materials, although the underlying mechanism is still controversial. We study long…
Phonon spectrum of PrZrO and PrIrO 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…
Unconventional free charge in the correlated semimetal Nd2Ir2O7
K. Wang, B. Xu, C. W. Rischau +9
Nd2Ir2O7 is a correlated semimetal with the pyrochlore structure, in which competing spin-orbit coupling and electron-electron interactions are believed to induce a time-reversal s…
Dielectric anomalies and interactions in the 3D quadratic band touching Luttinger semimetal PrIrO
Bing Cheng, T. Ohtsuki, Dipanjan Chaudhuri +3
Dirac and Weyl semimetals with linearly crossing bands are the focus of much recent interest in condensed matter physics. Although they host fascinating phenomena, their physics ca…
Spontaneous Hall effect induced by strain in PrIrO epitaxial thin films
Takumi Ohtsuki, Zhaoming Tian, Akira Endo +6
Strongly correlated iridate pyrochlores with geometrically frustrated spins have been recognized as a potentially interesting group of oxide materials where novel topological phase…
