Magnetic Energy of $T^{+}$ Particles

A plot of $U_B$ with changing $a=\cfrac{a_e}{r_e}$ ratio is shown below,

$r_e$ decreases with temperature, so $a=\cfrac{a_e}{r_e}$ increases with temperature.

The minimum point of $U_{B\,L}+U_{B\,R}$ increases along $\phi=\cfrac{\pi}{2}$ as the ratio $\cfrac{a}{r_e}$ increases with increasing temperature, up to $a\le\approx0.6$.  Above $a\approx0.6$, the value of $U_B$, first increases then decreases, the value of $U_B$ at $a=0.1$ is below the values of $U_B$ at $a=0.9$.

$U_B$ is indicative of the paired electrons ability to hold $T^{+}$ particles in its $B$ orbits.  At high temperature, the paired electrons is comparatively weak at holding on to the $T^{+}$, the material in which the paired orbit electrons are part of, releases some of its $T^{+}$ particles and appears hotter than its ambient temperature.

Have a nice day.
