New highly-anisotropic Rh-based Heusler compound for magnetic recording
Yangkun He, Gerhard H. Fecher, Chenguang Fu +18
The development of high-density magnetic recording media is limited by the superparamagnetism in very small ferromagnetic crystals. Hard magnetic materials with strong perpendicula…
Giant topological longitudinal circular photo-galvanic effect in the chiral multifold semimetal CoSi
Zhuoliang Ni, K. Wang, Y. Zhang +10
The absence of mirror symmetry, or chirality, is behind striking natural phenomena found in systems as diverse as DNA and crystalline solids. A remarkable example occurs when chira…
Pressure tuning of the anomalous Hall effect in the chiral antiferromagnet Mn3Ge
R. D. dos Reis, M. Ghorbani Zavareh, M. O. Ajeesh +9
We report on the pressure evolution of the giant anomalous Hall effect (AHE) in the chiral antiferromagnet MnGe. The AHE originating from the non-vanishing Berry curvature in M…
Direct observation of handedness-dependent quasiparticle interference in the two enantiomers of topological chiral semimetal PdGa
Paolo Sessi, Feng-Ren Fan, Felix Küster +16
It has recently been proposed that combining chirality with topological band theory may result in a totally new class of fermions. These particles have distinct properties: they ap…
Linear and nonlinear optical responses in the chiral multifold semimetal RhSi
Zhuoliang Ni, B. Xu, M. A. Sanchez-Martinez +8
Chiral topological semimetals are materials that break both inversion and mirror symmetries. They host interesting phenomena such as the quantized circular photogalvanic effect (CP…
Optical signatures of multifold fermions in the chiral topological semimetal CoSi
B. Xu, Z. Fang, M. A. Sánchez-Martínez +12
We report the optical conductivity in high-quality crystals of the chiral topological semimetal CoSi, which hosts exotic quasiparticles known as multifold fermions. We find that th…
Flux growth of Sr(n+1)Ir(n)O(3n+1) [n=1, 2, infinity] crystals
Kaustuv Manna, Gizem Aslan-Cansever, Andrey Maljuk +3
Single crystals of iridates are usually grown by a flux method well above the boiling point of the SrCl2 solvent. This leads to non-equilibrium growth conditions and dramatically s…
Visualizing higher-fold topology in chiral crystals
Tyler A Cochran, Ilya Belopolski, Kaustuv Manna +21
Novel topological phases of matter are fruitful platforms for the discovery of unconventional electromagnetic phenomena. Higher-fold topology is one example, where the low-energy d…
Discovery of topological Weyl fermion lines and drumhead surface states in a room temperature magnet
Ilya Belopolski, Kaustuv Manna, Daniel S. Sanchez +20
Topological matter is known to exhibit unconventional surface states and anomalous transport owing to unusual bulk electronic topology. In this study, we use photoemission spectros…
Zero-field Nernst effect in a ferromagnetic kagome-lattice Weyl-semimetal Co3Sn2S2
Satya N. Guin, Praveen Vir, Yang Zhang +10
The discovery of magnetic topological semimetals recently attracted significant attention in the field of topology and thermoelectrics. In a thermoelectric device based on the Nern…
Observation of giant spin-split Fermi-arc with maximal Chern number in the chiral topological semimetal PtGa
Mengyu Yao, Kaustuv Manna, Qun Yang +14
Non-symmorphic chiral topological crystals host exotic multifold fermions, and their associated Fermi arcs helically wrap around and expand throughout the Brillouin zone between th…
