Types Of Superconductors01:28

Types Of Superconductors

1.1K
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

1.2K
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...

Theory of Metallic Conduction

1.4K
The conduction of free electrons inside a conductor is best described by quantum mechanics. However, a classical model makes predictions close to the results of quantum mechanics. It is called the theory of metallic conduction.
In this theory, Newton's second law of motion is used to determine the acceleration of an electron in the presence of an applied electric field. Then, its velocity is expressed via this acceleration.
An electron moves through the crystal, containing positive ions,...

Ferromagnetism01:31

Ferromagnetism

2.5K
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...

Colors and Magnetism

12.3K
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...

Metal-Semiconductor Junctions

522
The contact of metal and semiconductor can lead to the formation of a junction with either Schottky or Ohmic behavior.
Schottky Barriers
Schottky barriers arise when a metal with a work function (Φm) contacts a semiconductor with a different work function (Φs). Initially, electrons transfer until the Fermi levels of the metal and semiconductor align at equilibrium. For instance, if Φm > Φs, the semiconductor Fermi level is higher than the metal's before contact. The...

Area of Science:

  • Materials Science
  • Condensed Matter Physics
  • Superconductivity

Background:

  • High-entropy alloys (HEAs) are a class of materials with unique properties.
  • Investigating the effects of specific elements on HEA properties is crucial for material design.
  • Superconducting HEAs offer potential for advanced technological applications.

Purpose of the Study:

  • To synthesize and characterize a superconducting alloy containing terbium (Tb).
  • To evaluate the impact of Tb addition on the alloy's structural and superconducting properties.
  • To compare the Tb-containing alloy with a reference alloy lacking Tb.

Main Methods:

  • Synthesis of superconducting alloys with and without terbium.
  • X-ray diffraction (XRD) for structural analysis.
  • Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) for compositional analysis.
  • Specific heat and magnetic measurements to determine superconducting properties.

Main Results:

  • Both alloys crystallized in a body-centered cubic structure.
  • Small amounts of terbium (Tb) and terbium oxide (Tb2O3) phases were detected in the Tb-containing alloy.
  • The critical temperature (Tc) ranged from 4.6-5.2 K, and the upper critical field (μ0Hc2) was 6.1-6.8 T.
  • Terbium addition did not significantly enhance the superconducting critical temperature or upper critical field.

Conclusions:

  • Terbium (Tb) addition to this specific high-entropy alloy does not improve its superconducting characteristics.
  • The presence of Tb and Tb2O3 phases may influence phase stability.
  • Understanding the role of lanthanides in superconducting HEAs is important for future alloy development.
