Temperature-dependent magnetization in a ferromagnetic bilayer consisting of two materials with different Curie temperatures

A structure-dependent self-consistent mean-field model has been used to calculate the temperaturedependent magnetization in ferromagnetic bilayers that consist of two materials with different Curie temperatures. The magnetization versus temperature curves fSsTdg are found to be structure sensitive among the bilayer systems with simple cubic, face-centered-cubic, and body-centered-cubic structur...

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...

High curie temperature ternary piezoelectric ceramics

A preferred piezoelectric ceramic material is a BiFeO3—PbZrO3—PbTiO3 ternary solid solution wherein proportions of the constituent perovskite metal oxides are selected so that the material exhibits relatively high Curie temperatures above 380° C. and useful piezoelectric properties.
