Magnetic order close to superconductivity in the iron-based layered LaO1-xFxFeAs systems
Clarina Dela Cruz,Clarina Dela Cruz,Qingzhen Huang,J. W. Lynn,Jiying Li,Jiying Li,William Ratcliff,Jerel L. Zarestky,Herbert A. Mook,G. F. Chen,J. L. Luo,Nan Wang,Pengcheng Dai,Pengcheng Dai +13 more
TL;DR: The role of magnetism in the superconductivity that occurs when mobile 'electrons' or 'holes' are doped into the antiferromagnetic parent compounds of rare-earth iron-based oxide systems was investigated in this paper.
Journal ArticleDOI
Neutron-Diffraction Measurements of Magnetic Order and a Structural Transition in the Parent BaFe 2 As 2 Compound of FeAs-Based High-Temperature Superconductors
Qingzhen Huang,Yiming Qiu,Yiming Qiu,Wei Bao,Mark Green,Mark Green,J. W. Lynn,Y. C. Gasparovic,Y. C. Gasparovic,Tao Wu,Gang Wu,X. H. Chen +11 more
TL;DR: In this paper, a tetragonal-to-orthorhombic distortion associated with the onset of the antiferromagnetic order in the FeAs-based materials was found.
Journal ArticleDOI
Structural and magnetic phase diagram of CeFeAsO 1− x F x and its relation to high-temperature superconductivity
Jun Zhao,Qingzhen Huang,Clarina Dela Cruz,Clarina Dela Cruz,Shiliang Li,J. W. Lynn,Yuanzhen Chen,Yuanzhen Chen,Mark Green,Mark Green,G. F. Chen,Gang Li,Zheng-Cai Li,J. L. Luo,Nan Wang,Pengcheng Dai,Pengcheng Dai +16 more
TL;DR: Comparison of the structural evolution of CeFeAsO(1-x)F(x) with other Fe-based superconductors suggests that the structural perfection of the Fe-As tetrahedron is important for the high-Tc superconductivity in these Fe pnictides.
Journal ArticleDOI
First-order magnetic and structural phase transitions in Fe1+ySexTe1-x
Shiliang Li,Clarina Dela Cruz,Clarina Dela Cruz,Qingzhen Huang,Ying Chen,J. W. Lynn,Jiangping Hu,Yi-Lin Huang,F. C. Hsu,Kuo-Wei Yeh,Maw-Kuen Wu,Pengcheng Dai,Pengcheng Dai +12 more
TL;DR: In this paper, the structural and magnetic phase transitions in Fe1+ySexTe1-x.068Te exhibits a first-order phase transition near 67 K with a tetragonal-to-monoclinic structural transition and simultaneously develops a collinear antiferromagnetic (AF) order responsible for the entropy change across the transition.
Journal ArticleDOI
Unconventional ferromagnetic transition in La1-xCaxMnO3.
TL;DR: In this article, the magnetic correlations and long-wavelength spin dynamics of a ferromagnetic regime were studied using neutron scattering in the presence of an anomalous strongly field-dependent diffusive component.
