  Two-dimensional (2D) chromium telluride Cr2Te3 exhibits strong ferromagnetic
ordering with high coercivity at low temperatures and paramagnetic behaviour
when approaching room temperature. The spin states of monolayer Cr2Te3 show
ferromagnetic ordering in the ground state, and in-situ Raman analysis shows
reversible structure transformation and hence a ferromagnetic to paramagnetic
transition during low-temperature heating cycles (0 - 25 {\deg}C). The magnetic
phase transition near room temperature in the 2D Cr2Te3 prompted the
exploration of these layered materials for energy application. We demonstrate
that the low-temperature ferromagnetic behavior can be used to magnetically
deice material surfaces using an external magnetic source, avoiding the use of
harsh chemicals and high temperatures. The hydrophobic nature and dipole
interactions of H2O molecules with the surface of the 2D Cr2Te3 coating aid in
the condensation of ice droplets formed on the surface. First-principles
calculations also confirm the observed crystal structure, surface interaction,
and magnetic properties of 2D Cr2Te3.
