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...

Magnetic domain formation in itinerant metamagnets.

We examine the effects of long-range dipolar forces on metamagnetic transitions and generalize the theory of Condon domains to the case of an itinerant electron system undergoing a first-order metamagnetic transition. We demonstrate that, within a finite range of the applied field, dipolar interactions induce a spatial modulation of the magnetization in the form of stripes or bubbles. Our findi...

Magnetoelastic Effects in UNiAl and UCoAl

We report on strongly anisotropic thermal-expansion and magnetostriction of UNiAl and UCoAl within the frame of the 5f -electron magnetism. Both the compounds crystallize in the hexagonal ZrNiAl-type structure and exhibit huge magnetocrystalline anisotropy with the c-axis as the easy magnetization direction. UNiAl orders antiferromagnetically (TN ≈ 19 K) and exhibits a field-induced metamagneti...

Concentration Dependence of Pressure Effect in La(Fe_{x}Si_{1-x})_{13} Compounds

Effects of pressure P on the magnetic momentM and the Curie temperature TC have been investigated for La(FexSi1 x)13 above and below the magnetic phase boundary concentration x 1⁄4 0:86, where the ferromagnetic-paramagnetic transition at TC changes from the first-order (x 0:86) to the second-order (x < 0:86). The pressure coefficient ofM exhibits a sluggish variation against concentration and n...

MAGNETOVOLUME EFFECT IN FERROMAGNETIC METALS : NUMERICAL RESULTS FOR BCC Fe AND FCC Ni

The magnetovolume effect in ferromagnetic bcc Fe and fcc Ni is estimated numerically in the fixed moment method by using the LMTO method and the local spin density approximation. The obtained results are compared with the experimental results. The magnetovolume effect is discussed by using the local spin density approximation [I-31 or by using the Stoner model where the volume dependence of the...
