A 3D quantum Hall effect has been reported in Dirac semimetal ZrTe5 due to a magnetic-field-driven Fermi surface instability. Here, the authors show evidence of quasi-quantized Hall response without Fermi surface instability, but they argue that it i

By examining the Ho2Fe14B case, we explored the influence of substitution and absorption atoms on the high-field behavior of magnetization of rare-earth (R)-Fe intermetallics. The value of the first critical field shows that the inter-sublattice exch

Noncollinear magnetic structure in U_{2}Pd_{2}In at high magnetic fields
Autor: K. Prokeš, M. Bartkowiak, D. I. Gorbunov, O. Prokhnenko, O. Rivin, P. Smeibidl
Publikováno v: Physical Review Research, Vol 2, Iss 1, p 013137 (2020)
We report an unexpected magnetic-field-driven magnetic structure in the 5f-electron Shastry-Sutherland system U_{2}Pd_{2}In. This phase develops at low temperatures from a noncollinear antiferromagnetic ground state above the critical field of 25.8 T

Magnetocaloric effect and spin-strain coupling in the spin-nematic state of LiCuVO_{4}
Autor: M. Gen, T. Nomura, D. I. Gorbunov, S. Yasin, P. T. Cong, C. Dong, Y. Kohama, E. L. Green, J. M. Law, M. S. Henriques, J. Wosnitza, A. A. Zvyagin, V. O. Cheranovskii, R. K. Kremer, S. Zherlitsyn
Publikováno v: Physical Review Research, Vol 1, Iss 3, p 033065 (2019)
We report on the magnetocaloric effect and ultrasound studies of the frustrated quasi-one-dimensional spin-1/2 compound LiCuVO_{4}, evidencing a spin-nematic state. The magnetic Grüneisen parameter diverges at the transition to the spin-nematic phas

International audience; We report that the local Ising anisotropy in pyrochlore oxides-the crucial requirement for realizing the spin-ice state-can be broken by means of high magnetic fields. For the case of the well-established classical spin-ice co
