Describe the atomic structure of the atom and its subatomic particles. What are the properties of noble gases? What is the binding energy of deuterium? What are the physical properties of transition metals? What is the term for the ability of an atom in a chemical bond to attract a shared...
The magnetic properties of pure transition-like metals are discussed within the single site approximation, to take into account the electron correlation. The metal is described by two hybridized bands one of which includes the Coulomb correlation. Our results indicate that ferromagnetism follows from ...
