Types Of Superconductors

1.7K
A superconductor is a substance that offers zero resistance to the electric current when it drops below a critical temperature. Zero resistance is not the only interesting phenomenon as materials reach their transition temperatures. A second effect is the exclusion of magnetic fields. This is known as the Meissner effect. A light, permanent magnet placed over a superconducting sample will levitate in a stable position above the superconductor. High-speed trains that levitate on strong...

Superconductor

A substance that reaches superconductivity, a state in which magnetic fields cannot penetrate, and there is no electrical resistance, is referred to as a superconductor. In 1911, Heike Kamerlingh Onnes of Leiden University, a Dutch physicist, observed a relation between the temperature and the resistance of the element mercury. The mercury sample was then cooled in liquid helium to study the linear dependence of resistance on temperature. It was observed that, as the temperature decreased, the...

Ferromagnetism

2.8K
Materials like iron, nickel, and cobalt consist of magnetic domains, within which the magnetic dipoles are arranged parallel to each other. The magnetic dipoles are rigidly aligned in the same direction within a domain by quantum mechanical coupling among the atoms. This coupling is so strong that even thermal agitation at room temperature cannot break it. The result is that each domain has a net dipole moment. However, some materials have weaker coupling, and are ferromagnetic at lower...

Valence Bond Theory

8.9K
Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Hybridization of Atomic Orbitals I03:24

Hybridization of Atomic Orbitals I

51.7K
The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an isolated atom. When atoms are bound together in a molecule, the wave functions combine to produce new mathematical descriptions that have different shapes. This process of combining the wave functions for atomic orbitals is called hybridization and is mathematically accomplished by the linear combination of atomic orbitals. The new orbitals that...

Area of Science:

  • Condensed Matter Physics
  • Materials Science
  • Superconductivity

Background:

  • Superconductivity in single-layer FeSe films on SrTiO3 substrates reaches high transition temperatures (Tc) due to electron transfer and tensile strain.
  • The parent compound BaFe2As2, a common iron-based superconductor, typically exhibits no bulk superconductivity without doping.

Purpose of the Study:

  • To investigate the induction of superconductivity in BaFe2As2 thin films solely through tensile lattice strain, without charge doping.
  • To explore the relationship between strain, structural changes, and superconductivity in epitaxial BaFe2As2 films.

Main Methods:

  • Epitaxial growth of BaFe2As2 thin films on Fe-buffered MgAl2O4 single crystalline substrates.
  • Utilizing lattice misfit between the film and substrate to induce tensile strain.
  • Investigating the suppression of antiferromagnetic spin density waves and the emergence of superconductivity.

Main Results:

  • Tensile lattice strain, induced by interfacial bonding and lattice misfit, successfully realized superconductivity in BaFe2As2.
  • Superconductivity was achieved with a bulk critical temperature (Tc) of approximately 10 K.
  • The applied strain suppressed the antiferromagnetic spin density wave state.

Conclusions:

  • Structural modifications, specifically tensile lattice strain, are crucial for controlling the phase diagram of iron-based superconductors.
  • Superconductivity can be induced in parent compounds like BaFe2As2 by manipulating lattice structure, offering an alternative to chemical doping.
