Another interesting finding of the study showed researchers could control and vary the temperature at which CGT lost its magnetism - a property known as Curie temperature
They not only went beyond the Curie temperature
(the temperature in which certain materials lose their magnetic properties, replaced by induced magnetism), they went beyond the critical end point (in which a liquid and its vapor can coexist).
The material design will be driven by automated large computational screening of new and novel intermetallic compounds with uniaxial structure in order to achieve high saturation magnetisation, magnetocrystalline anisotropy and Curie temperature
It also exhibits ferroelectric properties with Curie temperature
of 810C [7, 8].
Abolghasem Ataei, the project manager, said the most important issue in such treatment is to properly set the temperature known as Curie temperature
where the nanoparticles lose their magnetism and their temperature will not increase.
It can be noticed that the pyrolysis reaction of oil shale is slow when the Curie temperature
is below 386[degrees]C, and becomes intense above 423[degrees]C.
For very low-level signals, reaching the Curie temperature
is not a concern, but thermal offset voltages still can be generated by heating within the relay structure.
Among the topics are the technical viability of biocoke from mixtures of coal and wood charcoal for use in ironmaking, the effect of batch charging equipment on glass furnace efficiency, software for energy education, measuring the carbon dioxide captures on bauxite residue carbonation, anisotropic Curie temperature
material, and designing permanent magnet machines for ferrofluid immersion.
The morphology and performance of the material are related to the annealing temperature, time, and heating/ cooling rates [12, 20, 22, 29-31], For P(VDF-TrFE) copolymers, the annealing temperature between the Curie temperature
3]/BST) material is one of the ferroelectric material which attract great interest among researchers to study its electrical properties due to high dielectric constant and composition dependent Curie temperature
The Curie temperature
is an important characteristic of a permanent magnet.
A magnetocaloric material exhibits a strong magnetocaloric effect near the Curie temperature
, when the phase changes from paramagnetic to ferromagnetic.
