Oscillatory curie temperature of two-dimensional ferromagnets.
The effective exchange interactions of magnetic overlayers Fe/Cu(001) and Co/Cu(001) covered by a Cu-cap layer of varying thickness were calculated in real space from first principles. The effective two-dimensional Heisenberg Hamiltonian was constructed and used to estimate magnon dispersion laws, spin-wave stiffness constants, and overlayer Curie temperatures within the mean-field and random-p...
متن کاملPRESSURE EFFECT ON CURIE TEMPERATURE FOR Co1-xBx AMORPHOUS ALLOYS
Pressure effect on Curie temperature, dTc/dp, for amorphous Col-,B, alloys is estimated indirectly from forced volume magnetostriction even in Tc > Tcry. Results estimated indirectly show smaller values compared with those measured directly, and are consistent with thermal expansion. The value of dTc/dp extrapolated to Co agrees with that for crystalline Co.
متن کامل00 2 Plasticity of Ferromagnets near the Curie Point
We propose an explanation of the anomalous growth of plasticity in ferromagnets near the Curie point. We demonstrate that this effect is caused by spin-dependent detachment of dislocations from obstacles under an influence of the internal magnetic field. Magnetization fluctuations grow in the vicinity of the Curie point, yield an increase of the detachment probability and, hence, an increase of...

Curie Temperatures for Binary Ising Ferromagnets on the Square Lattice
High-accuracy Swendsen and Wang Monte Carlo simulations were performed to study the Curie temperature of ferromagnetic, binary Ising systems on the square lattice. Our results are compared with mean-field like approaches. Based on these former theories, we give a new formula to estimate the Curie temperature of the system. PACS number(s): 75.10H; 75.20E; 75.40M
