Here, we investigate the ordered double transition metal MXenes (W$_{2}$M$_{2}$C$_{3}$T$_{2}$, M = Nb, Ta, or V; T = O or F) using first-principles calculations. We predict four MXenes, (W$_{2}$Ta$_{2}$C$_{3}$O$_{2}$, W$_{2}$Nb$_{2}$C$_{3}$O$_{2}$, W$_{2}$V$_{2}$C$_{3}$O$_{2}$, and W$_{2}$V$_{2}$C$_{3}$F$_{2}$ to exhibit nontrivial topological phases. Orbital analysis shows that the d orbitals of W and M atoms are the main contributors in the low energy physics of W$_{2}$M$_{2}$C$_{3}$T$_{2}$. The results of the study provides potential candidates of topological materials for experimental realization and spintronics application.}, year = {2022}, booktitle = {Proceedings of the 40th Samahang Pisika ng Pilipinas Physics Conference}, pages = {SPP-2022-3E-02}, month = {19{\textendash}21 Oct 2022}, address = {Legazpi City}, url = {https://proceedings.spp-online.org/article/view/SPP-2022-3E-02}, }
