The Curie–Weiss law describes the magnetic susceptibility χ of a ferromagnet in the paramagnetic region above the Curie point: $${\displaystyle \chi ={\frac {C}{T-T_{\rm {C}}}}}$$where C is a material-specific Curie constant, T is the absolute temperature, and TC is the Curie temperature, both measured in kelvin. The law … See more The magnetic moment of a magnet is a quantity that determines the torque it will experience in an external magnetic field. A loop of electric current, a bar magnet, an electron, a molecule, and a planet all have magnetic moments. See more According to the Bohr–van Leeuwen theorem, when statistical mechanics and classical mechanics are applied consistently, the … See more In the presence of a uniform external magnetic field $${\displaystyle B}$$ along the z-direction, the Hamiltonian of the atom changes by See more • Curie's law • Paramagnetism • Pierre Curie • Pierre-Ernest Weiss • Exchange interaction See more In many materials, the Curie–Weiss law fails to describe the susceptibility in the immediate vicinity of the Curie point, since it is based on a mean-field approximation. Instead, there is a critical behavior of the form See more We take a very simple situation in which each atom can be approximated as a two state system. The thermal energy is so low that the atom is in the ground state. In this ground state, the … See more So far, we have assumed that the atoms do not interact with each other. Even though this is a reasonable assumption in the case of … See more WebWithin the temperature interval of 4.2K to 400 K, the magnetic susceptibility is described by the Curie‐Weiss law, χ= C / ( T −Θ) + χ dia, with the constant C corresponding to S … WebApr 3, 2024 · a) DC magnetic susceptibility (χ = M/B) as a function of temperature for B = 0.1 T along the c-axis (left axis).
