Journal ArticleDOI
Magnetic structure of EuFe 2 As 2 determined by single-crystal neutron diffraction
Yinguo Xiao,Yixi Su,M. Meven,Ranjan Mittal,Ranjan Mittal,C. M. N. Kumar,Tapan Chatterji,S. Price,Jörg Persson,Neeraj Kumar,S. K. Dhar,Arumugam Thamizhavel,Th. Brueckel +12 more
TL;DR: In this article, a single crystal neutron diffraction study was carried out to determine the magnetic structure of EuFe2As2 and investigate the coupling of two magnetic sublattices.
Journal ArticleDOI
Magnetic order in the CaFe 1-x Co x AsF (x=0.00,0.06,0.12) superconducting compounds
Yinguo Xiao,Yixi Su,Ranjan Mittal,Ranjan Mittal,Tapan Chatterji,Thomas Willum Hansen,C. M. N. Kumar,S. Matsuishi,Hideo Hosono,Th. Brueckel +9 more
TL;DR: In this paper, a neutron powder-diffraction experiment was performed to investigate the structural phase transition and magnetic order in the parent compound CaFeAsF and showed that the long-range antiferromagnetic order coexist with superconductivity in the orthorhombic phase of the underdoped compound.
Journal ArticleDOI
Observation of spin glass state in weakly ferromagnetic Sr2FeCoO6 double perovskite
R. Pradheesh,Harikrishnan S. Nair,C. M. N. Kumar,Jagat Lamsal,R. Nirmala,P. N. Santhosh,William B. Yelon,S. K. Malik,V. Sankaranarayanan,K. Sethupathi +9 more
TL;DR: In this paper, a spin glass state is observed in the double perovskite oxide Sr2FeCoO6 prepared through sol-gel technique, which shows that the compound crystallizes in tetragonal I4/m structure with lattice parameters.
Journal ArticleDOI
A single crystal X-ray and powder neutron diffraction study on NASICON-type Li1+xAlxTi2−x(PO4)3 (0 ≤ x ≤ 0.5) crystals: Implications on ionic conductivity
Günther J. Redhammer,Daniel Rettenwander,Sylke Pristat,Enkhtsetseg Dashjav,C. M. N. Kumar,Dan Topa,Frank Tietz +6 more
TL;DR: In this paper, single crystals of NASICON-type material Li1+xTi2−xAlx(PO4)3 (LATP) with 0.5 were successfully grown using long-term sintering techniques.
