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...

Diamagnetism01:26

Diamagnetism

2.5K
Materials consisting of paired electrons have zero net magnetic moments. However, when these materials are placed under an external magnetic field, the moments opposite to the field are induced. Such materials are called diamagnets. Diamagnetism is the response of the diamagnets when placed in an external magnetic field.
Diamagnetism was discovered by Anton Brugmans in 1778 when he observed that bismuth gets repelled by magnetic fields, thus theorizing that diamagnets get repelled by magnets....

Magnetic Susceptibility and Permeability01:31

Magnetic Susceptibility and Permeability

1.5K
In linear magnetic materials, like paramagnets and diamagnets, magnetization is proportional to the magnetic field intensity. The constant of proportionality, a dimensionless number, is called magnetic susceptibility. The value of the susceptibility depends on the type of material.
When diamagnetic materials are placed under an external magnetic field, the moments opposite to the field are induced. Hence, the susceptibility for diamagnets has a minimal negative value of 10-5–10-6. Since...

Paramagnetism01:30

Paramagnetism

2.6K
Paramagnets are materials with unpaired electrons that possess a finite magnetic moment. In the absence of a magnetic field, these moments are randomly oriented, and thus the net moment is zero. Under an external field, a torque acting on the moments tends to align them along the field's direction. However, the random thermal motion of electrons produces a torque opposite to the external field and tries to disorient the moments. These two competing effects align only a few moments along the...

Theory of Metallic Conduction01:17

Theory of Metallic Conduction

1.5K
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,...

Biasing of Metal-Semiconductor Junctions01:27

Biasing of Metal-Semiconductor Junctions

349
Biasing metal-semiconductor junctions involves applying a voltage across the junction. Specifically, the metal is connected to a voltage source, while the semiconductor is grounded. This technique is essential for controlling the direction and magnitude of current flow in electronic devices, including diodes, transistors, and photovoltaic cells.
In Schottky junctions, where the semiconductor is n-type, applying a positive voltage to the metal relative to the semiconductor reduces its Fermi...

Area of Science:

  • Materials Science
  • Crystallography
  • Organic Electronics

Background:

  • Shape memory alloys exhibit shape memory effects and superelasticity due to reversible martensitic phase transformations, widely used in various applications.
  • Ferroic materials typically lack memory effects for their ferroic domains after reversible phase transformations, limiting their potential in smart devices.

Purpose of the Study:

  • To investigate the existence of ferroic domain memory effects in single-component organic enantiomorphic ferroelectric/ferroelastic crystals.
  • To explore the control of ferroic domain patterns through both thermodynamic and light-driven phase transformations.

Main Methods:

  • Synthesis and characterization of single-component organic enantiomorphic ferroelectric/ferroelastic crystals: (R)- and (S)-N-3,5-di-tert-butylsalicylidene-1-(1-naphthyl)ethylamine (SA-NPh-(R) and SA-NPh-(S)).
  • Observation of ferroic domain pattern changes during reversible thermodynamic phase transformations (P1 to P21).
  • Investigation of ferroic domain pattern changes during reversible light-driven phase transformations induced by enol-keto photoisomerization (P1 to P21).

Main Results:

  • Ferroic domain patterns in SA-NPh-(R) and SA-NPh-(S) crystals disappear and reappear during reversible thermodynamic phase transformations.
  • Ferroic domain patterns in SA-NPh-(R) and SA-NPh-(S) crystals also disappear and reappear during reversible light-driven phase transformations.
  • The reappeared domain patterns are identical to the initial patterns, confirming a distinct domain memory effect.

Conclusions:

  • The study demonstrates a novel domain memory effect in ferroic materials, triggered by both thermodynamic and light-driven phase transformations.
  • This discovery opens new avenues for developing smart ferroic materials with thermal and optical control capabilities.
  • The findings challenge the conventional understanding of memory effects in ferroic materials.
