Magnetism of a sigma-phase Fe60V40 alloy: magnetic susceptibilities and magnetocaloric effect studies
M. Balanda, S. M. Dubiel, R. Pelka
Magnetic properties of a sigma-phase Fe60V40 intermetallic compound were studied by means of ac and dc magnetic susceptibility and magnetocaloric effect measurements. The compound…

A general discussion of the simulation procedure of the full susceptibility tensor and isothermal magnetization pseudovector for compounds comprising weakly-interacting magnetic ce…
Magnetic systems at criticality: different signatures of scaling
R. Pelka, P. Konieczny, M. Fitta +8
Different aspects of critical behaviour of magnetic materials are presented and discussed. The scaling ideas are shown to arise in the context of purely magnetic properties as well…

Magnetocaloric effect in {[Fe(pyrazole)][Nb(CN)]4HO} molecular magnet is reported. It crystallizes in tetragonal I4/a space group. The compound exhib…
Perturbative expansion for the half-integer rectilinear disclination line in the Landau-de Gennes theory
H. Arodz, R. Pelka
The structure of the half-integer rectilinear disclination line within the framework of the Landau-de Gennes effective theory of nematic liquid crystals is investigated. The consis…
Remarks on the n=1/2 disclination line in Landau-de Gennes theory of nematic liquid crystals
H. Arodź, R. Pełka
Using Landau-de Gennes effective theory for nematic liquid crystals we analyse the structure of rectilinear n=1/2 smooth disclination line in the case of equal elastic constants. W…
Perturbations of planar interfaces in Ginzburg-Landau models
H. Arodz, R. Pelka, L. Stepien
Certain dissipative Ginzburg-Landau models predict existence of planar interfaces moving with constant velocity. In most cases the interface solutions are hard to obtain because pe…
Evolution of interfaces and expansion in width
H. Arodz, R. Pelka
Interfaces in a model with a single, real nonconserved order parameter and purely dissipative evolution equation are considered. We show that a systematic perturbative approach, ca…
Backreaction of excitations on a domain wall
R. Pelka
Backreaction of excitations on a planar domain wall in a real scalar field model is investigated in the cases of homogeneous, plane wave and wave packet type excitations. It is fou…
