Negative Magnetoresistance in Dual Spin Valve Structures With a Synthetic Antiferromagnetic Free Layer
TL;DR: In this paper, a spin valve with a typical F/N/F structure exhibits negative magnetoresistance (GMR) due to spin-dependent scattering occurring at ferromagnet/normal metal interfaces and/or in the ferromagnetic layers.
MAGNETIC TRANSITIONS AND ANOMALOUS BEHAVIOUR OF PRASEODYMIUM IN Pr2 (Fe1-xCox)14 B
TL;DR: Mesure de la variation avec la composition des proprietes magnetiques de Pr 2 (Fe 1−x Co x ) 14, dont les champs d'anisotropie et les transitions magnetiques as mentioned in this paper.

Spin liquids and spin glasses in Mn-based alloys with the cubic A13 (βMn) structure
TL;DR: The magnetic susceptibility of pure βMn is ≈ 9Õ×10−4 from 4 to 400 K, but the field-cooled and zero-fieldcooled susceptibilities of all doped samples increase at low temperature and they bifurcate at a spin-freezing temperature Tf that increases with x, linearly at first.
