Magnetic Phase Transitions in Silicate Minerals
J. M. D. Coey,Subrata Ghose +1 more
- 01 Jan 1988
TL;DR: In this article, a phase transition to a collective, magnetically ordered state at low temperatures was shown in natural silicates with small amounts of 3d transition metal ions in octahedral sites.
Hydrogen induced metamagnetism in R6Fe13X compounds
TL;DR: The ternary intermetallics R6Fe13X (R = Pr, Nd; X = Cu, Sb, Bi) all crystallize in the tetragonal Nd6Fe14Si structure.

Fecher,Chenguang Fu,Yu Pan,Kaustuv Manna,Johannes Kroder,Ajay Jha,Xiao Wang,Zhiwei Hu,Stefano Agrestini,Javier Herrero-Martín,Manuel Valvidares,Yurii Skourski,Walter Schnelle,Plamen Stamenov,Horst Borrmann,Liu Hao Tjeng,Rudolf Schaefer,Rudolf Schaefer,Stuart S. P. Parkin,J. M. D. Coey,Claudia Felser +21 more
TL;DR: The pronounced temperature dependence of the anisotropy that follows from its Tc of 450 K, together with a thermal conductivity of 20 W m-1 K-1 , make Rh2 CoSb a candidate for the development of heat-assisted writing with a recording density in excess of 10 Tb in.-2 .
Neutron imaging of liquid-liquid systems containing paramagnetic salt solutions

TL;DR: The method of neutron imaging was adopted to map the concentration evolution of aqueous paramagnetic Gd(NO3)3 solutions as mentioned in this paper, which can be used to counter density-difference driven convection.
Ce2Fe17: Mixed valence or 4f band?
TL;DR: In this article, the Ce2Fe17 compound has a volume that is 4% smaller than expected for a localized 4f1 configuration of cerium, and the Ce LIII absorption edge shows two peaks, at 5734 and 5740 eV.
