Collinear ferromagnetism with reduced moment length in kagome magnet Nd3Ru4Al12
Yuki Ishihara, Ryota Nakano, Rinsuke Yamada +14
We determine the magnetic ground state of the kagome lattice magnet Nd3Ru4Al12 by single-crystal neutron diffraction, supported by experiments with polarized neutrons. We identify…
Visualization of Co 3d high- and low-spin states via valence electron density
Kamini Gautam, Shunsuke Kitou, Yuiga Nakamura +5
Properties of trivalent cobalt oxides are governed by the spin and orbital states of Co3+ ions, which are strongly coupled to their local coordination environments and chemical bon…
XRD study of the magnetization plateau above 40 T in the frustrated helimagnet CuGaCrS
M. Gen, K. Noda, K. Shimbori +14
CuGaCrS, which contains a chromium breathing pyrochlore network, exhibits diverse magnetic phases, including an incommensurate helical state below 31 K and a 1/2-magnet…
X-ray free-electron laser observation of giant and anisotropic magnetostriction in -O at 110 Tesla
Akihiko Ikeda, Yuya Kubota, Yuto Ishii +18
In strong magnetic fields beyond 100 T, the significant Zeeman energy competes with the lattice interactions, where a considerable magnetostriction is expected. However, the micros…
Perfectly harmonic spin cycloid and multi- textures in the Weyl semimetal GdAlSi
Ryota Nakano, Rinsuke Yamada, Juba Bouaziz +18
A fundamental question concerns how topological electronic states are influenced by many-body correlations, and magnetic Weyl semimetals represent an important material platform to…
Coexistence of local structural heterogeneities and long-range ferroelectricity in Pb-free (1-x)Ba(Zr0.2Ti0.8)O3-x(Ba0.7Ca0.3)TiO3 ceramics
Koushik Dey, Abdul Ahad, Kamini Gautam +11
Environmentally benign (1-x)Ba(TiZr)O-x(BaCa)TiO (BZT-BCT) ceramics are promising materials due to their remarkable high piezoresponse [Liu…
Magnetic correlations in subsystems of the misfit [CaCoO][CoO] cobaltate
Abdul Ahad, K. Gautam, K. Dey +7
[CaCoO][CoO], a two dimensional misfit metallic compound, is famous for its rich phases accessed by temperature, high temperature spin-state transition,…
Origin of the high Seebeck coefficient of the misfit [CaCoO][CoO] cobaltate from site-specific valency and spin-state determinations
Abdul Ahad, K. Gautam, S. S. Majid +4
Layered misfit cobaltate [CaCoO][CoO], which emerged as an important thermoelectric material~[A. C. Masset et al. Phys. Rev. B, 62, 166 (2000)], has been explo…
Random magnetic anisotropy driven transitions in layered perovskite LaSrCoO
Abdul Ahad, K. Gautam, S. S. Majid +8
Attempts to unravel the nature of magnetic ordering in LaSrCoO (Co), a compound intermediate between antiferromagnetic (AFM) LaCoO (Co) and ferromagnetic…
Magnetic and orbital correlations in multiferroic CaMnO probed by x-ray resonant elastic scattering
K. Gautam, S. S. Majid, S. Francoual +6
The quadruple perovskite CaMnO is a topical multiferroic, in which the hierarchy of electronic correlations driving structural distortions, modulated magnetism, and orbi…
Role of the V-V dimerization in insulator-metal transition and optical transmittance of pure and doped VO2 thin films
S. S. Majid, S. R. Sahu, A. Ahad +7
Insulator to metal (IMT) transition (T 341 K) in the VO2 accompanies transition from an infrared (IR) transparent to IR opaque phase. Tailoring of the IMT and associated…
