How does the magnetization of gadolinium scale with temperature above the Curie temperature?
Best insight from top research papers
The magnetization of gadolinium scales with temperature above the Curie temperature. The behavior of the magnetization at temperatures below TC is not in agreement with some theoretical expectations and several experimental results for other ferromagnets . The magnetization reversal process in nanocrystalline gadolinium is governed by the shape anisotropy and the magnetocrystalline and magnetostatic fluctuations in the grain-boundary and interfacial regions . The value of the demagnetization factor N has a significant influence on the perceived location of TC on the temperature scale . Near the Curie temperature, the magnetic field dependence of the adiabatic temperature change is far from saturation and is adequately described by the thermodynamic Landau theory for magnetic second-order phase transitions . For higher magnetic fields, a complete disappearance of the maximum near TC and the emergence of a new very broad maximum far above TC is predicted .

What’s the curie temperature?4 answersThe Curie temperature is a critical temperature at which a material undergoes a phase transition from a ferromagnetic to a paramagnetic state. It is an important property for understanding the magnetic behavior of materials. The Curie temperature can be influenced by various factors such as the heating rate during thermogravimetric measurements, the structural parameters of the material, and the magnetic interactions within the material. Additionally, the Curie temperature can be affected by the presence of phonons and the feedback effect from phonons to magnetism. Understanding and predicting the Curie temperature is crucial for the design and development of ferromagnetic materials with desired magnetic properties.
Which magnetic shape memory alloy has highest magnetization change during martensitic transition?5 answersThe Ni45Co5Mn36In13.2Cu0.8 alloy has the highest magnetization change during the martensitic transition.
How do the magnetic and dielectric properties of ferroelectrics and ferromagnets with temperature?5 answersThe magnetic and dielectric properties of ferroelectrics and ferromagnets vary with temperature. In paramagnetic molecular ferroelectrics, magnetoelectric coupling occurs at room temperature, where the responses to magnetic fields and modifications of ferroelectricity have the same chemical origin. In bulk SrFe12O19, the spin moment of iron ions reorients below 50 K, leading to changes in the magnetic structure. The saturation magnetization and coercivity field show opposite tendencies with temperature. In magnetite (Fe3O4) single crystals, ac susceptibility and ac permittivity reveal similar relaxation processes at low temperatures, below the Verwey transition. In a Ni80Fe20/PbZr0.44Ti0.56O3 multiferroic heterostructure, the magnetoelectric coupling effect arises from the interfacial accumulation or depletion of spin-polarized electrons, rather than strain. The temperature dependence of magnetization and surface magnetic anisotropy is related to changes in the spin-polarized electron density due to thermal motion. In magnetic relaxor ferroelectrics, the dielectric constant exhibits a sharp increase around the magnetic phase-transition temperature, and the dielectric anomaly is attributed to the amendment of the activation energy against dipole reorientation by the spin-pair correlation via magnetoelectric coupling.
How does the Curie-Weiss temperature of Gadolinium vary with pressure?5 answersThe Curie temperature of gadolinium varies with pressure, and this variation is influenced by the Fermi surface structure. The pressure dependence of the Curie temperature has been studied using various methods, including the pseudoharmonic approximation approach. Experimental data on the temperature dependences of magnetization and magnetostriction have been used to estimate the change in Curie temperature with pressure, and the results are in good agreement with the experimental data. The pressure coefficients of the electrical resistivity and thermal conductivity of gadolinium have been measured, and it has been found that the lattice thermal conductivity has a strong pressure dependence. Additionally, the dielectric constant of (Ba0.06Sr0.94)TiO3 has been measured under hydrostatic pressure, and the critical exponent of the electric susceptibility shows sensitivity to variations in pressure.
