Here we study how this affects the spin-subband populations and the spin-polarization as functions of the temperature, &lt;span class=&quot;aps-inline-formula&quot;&gt;&lt;span id=&quot;MathJax-Element-1-Frame&quot; style=&quot;font-size: 117%;&quot; class=&quot;mjx-chtml MathJax_CHTML&quot;&gt;&lt;span id=&quot;MJXc-Node-1&quot; class=&quot;mjx-math&quot;&gt;&lt;span id=&quot;MJXc-Node-2&quot; class=&quot;mjx-mrow&quot;&gt;&lt;span id=&quot;MJXc-Node-3&quot; class=&quot;mjx-mi&quot;&gt;&lt;span style=&quot;padding-top: 0.43em; padding-bottom: 0.308em; padding-right: 0.12em;&quot; class=&quot;mjx-char MJXc-TeX-math-I&quot;&gt;T&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;, and the in-plane magnetic field, &lt;span class=&quot;aps-inline-formula&quot;&gt;&lt;span id=&quot;MathJax-Element-2-Frame&quot; style=&quot;font-size: 117%;&quot; class=&quot;mjx-chtml MathJax_CHTML&quot;&gt;&lt;span id=&quot;MJXc-Node-4&quot; class=&quot;mjx-math&quot;&gt;&lt;span id=&quot;MJXc-Node-5&quot; class=&quot;mjx-mrow&quot;&gt;&lt;span id=&quot;MJXc-Node-6&quot; class=&quot;mjx-mi&quot;&gt;&lt;span style=&quot;padding-top: 0.491em; padding-bottom: 0.308em;&quot; class=&quot;mjx-char MJXc-TeX-math-I&quot;&gt;B&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;, for narrow to wide dilute-magnetic-semiconductor quantum wells. We examine a wide range of material and structural parameters, focusing on the quantum well width, the magnitude of the spin-spin exchange interaction, and the sheet carrier concentration.

Furthermore, in line with the density of states modification, all energetically higher subbands become gradually depopulated. We also indicate the ranges where the system is completely spin-polarized.</style></abstract><notes><style face="normal" font="default" size="100%">cited By 13</style></notes></record></records></xml>
