Gapless spinons and a field-induced soliton gap in the hyper-honeycomb Cu oxalate framework compound [(CH)NH]Cu(CO)
C. Dissanayake, A. C. Jacko, K. Kumarasinghe +14
We report a detailed study of the specific heat and magnetic susceptibility of single crystals of a spin liquid candidate: the hyper-honeycomb Cu oxalate framework compound [(C…
Temperature-dependent Eu spin reorientations in the tetragonal A-type antiferromagnet EuGa induced by small ab-plane magnetic fields
Santanu Pakhira, David C. Johnston
The body-centered-tetragonal antiferromagnet EuGa exhibits A-type antiferromagnetic order below its Néel temperature K in magnetic field where the mo…
Anisotropic magnetism and electronic structure of trigonal EuAlGe single crystals
Santanu Pakhira, Asish K. Kundu, Farhan Islam +10
The magnetic and electronic properties of the layered Zintl-phase compound EuAlGe crystallizing in the trigonal CaAlSi-type structure are reported. Our neutron-diff…
Low-field magnetic anomalies in single crystals of the A-type square-lattice antiferromagnet EuGa
Santanu Pakhira, D. C. Johnston
The body-centered-tetragonal antiferromagnet EuGa was recently identified as a Weyl nodal-line semimetal that exhibits the topological Hall effect below its reported antiferrom…
Electronic and magnetic properties of the topological semimetal SmMgBi
Asish K. Kundu, Santanu Pakhira, Tufan Roy +7
Dirac semimetals show nontrivial physical properties and can host exotic quantum states like Weyl semimetals and topological insulators under suitable external conditions. Here, by…
Magnetic-field-induced ab-plane rotation of the Eu magnetic moments in trigonal EuMg2Bi2 and EuMg2Sb2 single crystals below their Neel temperatures
Santanu Pakhira, Yongbin Lee, Liqin Ke +1
The thermodynamic and electronic-transport properties of trigonal EuMg2Bi2 in ab-plane magnetic fields Hx and the A-type antiferromagnetic structure have recently been reported. At…
