With hypothermia, you can get a quantum material with emergent properties. If the glass contains a d-element, then with its low content in the material, the glass will have diamagnetic properties, and with an increase in the concentration of the d-element, paramagnetic properties. As the temperature decreases, the participation of the energy of the zero point of the glass in the collective interaction of electrons increases. An increase in the concentration of the d-element and a decrease in temperature will lead you to the discovery of emergent properties. You can see in our work the transition from diamagnetic to paramagnetic properties in aqueous solutions.

Temperature does not affect the diamagnetic material. So no matter how cool it is, it remains diamagnetic. For some materials, they show superconductivity at extremely low temperature. And they strongly repel the magnetic field.
