Valence Bond Theory

Valence Bond Theory

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...

Ferromagnetism

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...

Colors and Magnetism

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.

Diamagnetism

Diamagnetism

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.

Paramagnetism

Paramagnetism

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...

Imperfections in Crystal Structure: Stoichiometric Point Defects

Imperfections in Crystal Structure: Stoichiometric Point Defects

Schottky defects arise when some lattice points in a crystal, such as those in NaCl, remain unoccupied, creating lattice vacancies without disturbing the overall electrical neutrality of the crystal. This defect is common in ionic crystals where the positive and negative ions are similar in size, as seen in sodium chloride and cesium chloride. The presence of Schottky defects enables the crystal to conduct electricity to a small extent through an ionic mechanism. Electric fields cause nearby...

Summary

We studied orbital and magnetic ordering in bilayer manganites using resonant soft x-ray scattering. CE-type orbital order was observed, coexisting with coupled CE- and A-type antiferromagnetic orders.

Background:

Bilayer manganites exhibit complex electronic and magnetic properties.
Understanding orbital and magnetic ordering is crucial for their applications.

Purpose of the Study:

To investigate the orbital and antiferromagnetic ordering behaviors in La(2-2x)Sr(1+2x)Mn2O7 (x ≃ 0.5).
To elucidate the relationship between orbital order and magnetic orders.

Main Methods:

Mn L(2,3)-edge resonant soft x-ray scattering was employed.
Analysis of scattering patterns to determine orbital and magnetic structures.

Main Results:

CE-type orbital order was observed below T(oo) ≃ 220 K, with partial melting below T(m) ≃ 165 K.
Coexistence of CE- and A-type antiferromagnetic orders was found.
Both magnetic orders are coupled with the CE-type orbital order.

Conclusions:

The ground state with CE-type antiferromagnetic order is sensitive to doping fluctuations.
Small doping variations can destabilize the CE-type order into the A-type one.
Narrow magnetic phase boundaries at x ≃ 0.5±0.005 support this sensitivity.
