Superconductor

1.5K
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...

Types Of Superconductors

1.4K
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...

Ferromagnetism

2.7K
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...

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...

Specific Heat01:16

Specific Heat

65.5K
The specific heat capacity of a substance refers to the energy required to increase the temperature of one gram of that substance by one degree Celcius. Specific heat capacity is often represented in calories (cal), grams (g), and degrees Celsius (oC), but can also be expressed in joules (J), kilograms (kg), and Kelvin (K), among other units.
For example, increasing the temperature of one gram of water by 1°C requires one calorie of heat energy and can be written as 1 cal/g-°C, or...

Atomic Spectroscopy: Effects of Temperature01:27

Atomic Spectroscopy: Effects of Temperature

667
Atomization, converting samples into gas-phase atoms and ions, is essential for atomic spectroscopy. The flame temperature required for atomization affects the efficiency of the atomic spectroscopic methods by increasing the atomization efficiency and the relative population of the excited and ground states.
At thermal equilibrium, the relative populations of excited and ground state atoms can be estimated using the Maxwell–Boltzmann distribution. For example, an increase in temperature...

Area of Science:

  • Condensed Matter Physics
  • Materials Science
  • Superconductivity

Background:

  • Pressure-stabilized hydrides represent a rapidly advancing field of high-temperature superconductors.
  • These materials are generally understood through the conventional phonon-mediated coupling mechanism.

Purpose of the Study:

  • To synthesize and characterize yttrium hexahydride (YH6), a prominent high-temperature superconductor.
  • To investigate the superconducting properties of YH6, including its transition temperature, critical magnetic field, and critical current density.

Main Methods:

  • High-pressure synthesis of yttrium hexahydride (YH6).
  • Measurement of superconducting transition temperature (Tc) at approximately 224 K under 166 GPa.
  • Extrapolation of the upper critical magnetic field (Bc2(0)).
  • Isotope effect measurements using yttrium deuteride (YD6).
  • Current-voltage measurements to determine critical current (Ic) and critical current density (Jc).
  • Superconducting density functional theory (SCDFT) and anharmonic calculations.

Main Results:

  • Superconducting transition observed at approximately 224 K under 166 GPa for YH6.
  • Extrapolated upper critical magnetic field (Bc2(0)) of YH6 is significantly high (116-158 T), exceeding theoretical predictions.
  • A notable isotope coefficient (0.4) in YD6 supports phonon-assisted superconductivity.
  • Critical current density (Jc) exceeds 3500 A mm-2 at 4 K, surpassing commercial superconductors like NbTi and YBCO.

Conclusions:

  • The observed properties of YH6, particularly its high critical magnetic field, deviate from conventional Migdal-Eliashberg and Bardeen-Cooper-Schrieffer theories.
  • Evidence suggests the presence of an additional, non-conventional mechanism contributing to superconductivity in YH6.
  • Further theoretical and experimental investigations are warranted to fully understand the superconductivity in this material.
