Journal ArticleDOI
Spin chirality, Berry phase, and anomalous Hall effect in a frustrated ferromagnet.
TL;DR: The present combined work of transport measurement, neutron scattering, and theoretical calculation provides evidence that the gigantic anomalous Hall effect observed in Nd 2 Mo 2 O 7, a pyrochlore ferromagnet with geometrically frustrated lattice structure, is mostly due to the spin chirality and the associated Berry phase originating from the Mo spin tilting as mentioned in this paper.
Journal ArticleDOI
Magnetic Ordering and Relation to the Metal-Insulator Transition in Pr 1 − x Sr x MnO 3 and Nd 1 − x Sr x MnO 3 with x ∼ 1 / 2
TL;DR: In this article, the authors studied three distorted perovskite manganites, Pr{sub 1/2}Sr {sub 1 2}MnO {sub 3} and Nd{sub 0.45} Sr{sub0.55} MnO{sub 3] with x=1/2 and 0.55 by the neutron diffraction technique.
Journal ArticleDOI

TL;DR: In this paper, a peformed neutron diffraction measurements on melt-grown polycrystalline samples of the MnOµµ system was performed and a systematic transformation of the crystalline and magnetic structures of this system was observed.
Journal ArticleDOI
Neutron-diffraction study of the magnetic-field-induced metal-insulator transition in Pr0.7Ca0.3MnO3.
TL;DR: In this article, an applied field enforces a ferromagnetic spin alignment and drives the metal state into the metallic state by actuating the double exchange mechanism and destroying the charge ordering.
Journal ArticleDOI
Ferromagnetism-induced reentrant structural transition and phase diagram of the lightly doped insulator La 1 − x Sr x Mn O 3 ( x 0.17 )
TL;DR: In this article, the crystal structure of the lightly doped insulating system with $xl~0.17$ has been studied in detail using neutron diffraction and it has been established that this system has two orthorhombic phases.
