Types Of Superconductors01:28

Types Of Superconductors

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...
Ferromagnetism01:31

Ferromagnetism

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...
Network Covalent Solids02:18

Network Covalent Solids

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...
Colors and Magnetism03:02

Colors and Magnetism

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 eye.

Crystal Field Theory - Octahedral Complexes

Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...

Summary

Superconductivity in iron-based FeSe(0.5)Te(0.5) initially increases with pressure up to 3.6 GPa. Beyond this, superconductivity is lost as pressure increases, coinciding with structural changes.

Area of Science:

  • Condensed Matter Physics
  • Materials Science
  • Solid State Chemistry

Background:

  • Iron-based superconductors, such as FeSe(0.5)Te(0.5), exhibit unique electronic properties.
  • Understanding the influence of external stimuli like pressure is crucial for superconductor applications.

Purpose of the Study:

  • To investigate the high-pressure superconductivity of the iron-based superconductor FeSe(0.5)Te(0.5).
  • To determine the relationship between applied pressure, superconducting transition temperature (T(c)), and structural stability.

Main Methods:

  • Utilized a designer diamond anvil cell with an eight-probe setup for high-pressure electrical resistance measurements.
  • Performed four-probe resistance measurements up to 15 GPa and 10 K.
  • Correlated superconducting behavior with existing x-ray diffraction data on structural phase transitions.

Main Results:

  • Observed the onset of superconductivity at 14 K at ambient pressure.
  • Found that T(c) increased with pressure, reaching a maximum of 19 K at 3.6 GPa.
  • Reported a decrease in T(c) at pressures above 3.6 GPa, with superconductivity extrapolated to be lost above 10 GPa.
  • Noted that the loss of superconductivity correlated with pressure-induced disordering of Fe(SeTe)(4) tetrahedra.

Conclusions:

  • Superconductivity in FeSe(0.5)Te(0.5) is sensitive to applied pressure.
  • A structural phase transition around 11 GPa, involving the disordering of tetrahedra, is linked to the suppression of superconductivity.
  • Further research is needed to explore pressure-induced mechanisms affecting superconductivity in iron-based materials.
