The relation between $\\chi$ and $R_H$ depends on the origin of the<br \/>\nmagnetization process. In a normal metal, $\\chi$ is related to the electronic density of states at the<br \/>\nFermi energy, $D(E_F)$, as $\\chi = (\\mu_B\/N) D(E_F)$, where $N$ is the number of electrons per unit volume.<br \/>\nIn a semiconductor with a parabolic band, $\\chi$ is proportional to the carrier density $n$, as<br \/>\n$\\chi = (\\mu_B\/N) n$. In a ferromagnet, the relation between $R_H$ and $\\chi$ is more complicated,<br \/>\nbecause the spin-polarized band structure also plays an important role.<\/p>\n<p>For the case of InMn$_x$As alloys, the carriers are electrons. In the past, $R_H$ and $\\chi$ were<br \/>\nmeasured independently and were found to be consistent with the relation $R_H =<br \/>\n\\chi\/(\\chi^2+\\chi^2_0)$~\\cite{hsu_tesla_1994}, where $\\chi_0$ is the Curie susceptibility. This relation is<br \/>\nvalid when a material is close to the Curie point, and when $|\\chi|$ is much larger than $\\chi_0$. It<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Susceptibility_in_Physics\"><\/span>Susceptibility in Physics<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In physics, susceptibility is a measure of how easy it is to change the value of a physical quantity in response to an external influence. In other words, it measures how responsive a quantity is to a change in another quantity. For example, the electrical susceptibility of a material measures how easily the material can be electrically polarized in response to an external electric field.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Susceptibility_of_Magnetic_Material\"><\/span>Susceptibility of Magnetic Material<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The susceptibility of a magnetic material is a measure of the material&#8217;s ability to be magnetized in the presence of a magnetic field. The higher the susceptibility, the more easily the material can be magnetized. The susceptibility is also a measure of the material&#8217;s ability to interact with a magnetic field.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_Paramagnetic_Material\"><\/span>What is Paramagnetic Material<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>?<\/p>\n<p>A paramagnetic material is a material that is weakly attracted to a magnetic field.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"2_Diamagnetic_Material\"><\/span>2.
