The non-existence of Ga(II) compounds was part of the so-called inert-pair effect. When salts of the anion with empirical formula such as [GaCl 3] − were synthesized they were found to be diamagnetic. This implied the formation of a Ga-Ga bond and a dimeric formula, [Ga 2 Cl 6] 2−. [33]
Magnetochromism is the term applied when a chemical compound changes colour under the influence of a magnetic field.In particular the magneto-optical effects exhibited by complex mixed metal compounds are called magnetochromic when they occur in the visible region of the spectrum.
Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other.Because both electric currents and magnetic moments of elementary particles give rise to a magnetic field, magnetism is one of two aspects of electromagnetism.
These effects have been supposed to exist since the time of Michael Faraday. There have also been observations on the existence of Hall effect in electrolytes. Until these observations, magnetoelectrochemistry was an esoteric curiosity, though this field has had a rapid development in the past years and is now an active area of research.
Historically, the first and most studied example of this effect is the linear magnetoelectric effect.Mathematically, while the electric susceptibility and magnetic susceptibility describe the electric and magnetic polarization responses to an electric, resp. a magnetic field, there is also the possibility of a magnetoelectric susceptibility which describes a linear response of the electric ...
The magnetomechanical effect is a fundamental feature of ferromagnetism. The fact that the application of external stresses alters the flux density of a magnetized ferromagnet, and thus the shape, and size of its hysteresis loops is easily changeable.
A rendering of the magnetic field lines of the magnetosphere of the Earth.. In astronomy and planetary science, a magnetosphere is a region of space surrounding an astronomical object in which charged particles are affected by that object's magnetic field.
When cooled below a temperature called the Curie temperature, the magnetization of a piece of ferromagnetic material spontaneously divides into many small regions called magnetic domains. The magnetization within each domain points in a uniform direction, but the magnetization of different domains may point in different directions.
