Itinerant electron metamagnetism and magnetocaloric effect in RCo2-based Laves phase compounds

Itinerant electron metamagnetism and magnetocaloric effect in Dy(Co,Si)2

Itinerant electron metamagnetism in DyðCo1-xSixÞ2 compounds was studied in the light of a recent theoretical model based on magnetovolume effect and spin fluctuations. The nature of the magnetic transition in these compounds was analyzed within the framework of this model. The magnetocaloric effect in these compounds has been calculated and correlated with the strength of itinerant electron met...

Itinerant metamagnetism in TiBe2

2014 The high field magnetization data of Monod, Felner, Chouteau and Shaltiel [1] on TiBe2 are discussed in terms of a metamagnetic transition in fields about 5 T. J. Physique LETTRES 41 (1980) L-563 L-565 1 er DÉCEMBRE 1980,

Crystallography, anisotropic metamagnetism, and magnetocaloric effect in Tb5Si2.2Ge1.8

The metamagnetic-like transitions and giant magnetocaloric effect were observed with the magnetic field applied parallel to the aand c axes, but not the b axis in a Tb5Si2.2Ge1.8 single crystal. The in situ x-ray powder diffraction study indicates that these metamagnetic-like transitions are coupled to crystallographic phase transformations occurring via strong magnetoelastic interactions. The ...

Sequential Cobalt Magnetization Collapse in ErCo2: Beyond the Limits of Itinerant Electron Metamagnetism

The itinerant electron metamagnetism (IEM) is an essential physical concept, describing magnetic properties of rare earth - transition metal (R-TM) intermetallics, demonstrating technologically important giant magnetoresistance and magnetocaloric effects. It considers an appearance of TM magnetization induced by spontaneous magnetization of surrounding R atoms, which provides significant respon...
