  A two-dimensional superconducting adlayer grown on a magnetic topological
insulator (MTI) has the potential to exhibit proximity induced
superconductivity, facilitate the existence of Majorana fermions and find
applications in the field of quantum computing. In this work, we demonstrate
the formation of bilayer stanene on an MTI substrate, specifically
Mn(Bi$_{0.74}$Sb$_{0.26}$)$_2$Te$_4$ (MBST), through utilization of a
combination of techniques such as angle-resolved photoemission spectroscopy
(ARPES), scanning tunneling microscopy (STM), density functional theory (DFT),
x-ray photoelectron spectroscopy (XPS), and low energy electron diffraction
(LEED). The stanene related bands observed in ARPES have been corroborated by
our DFT calculations. Atomic resolution STM topography images confirm the
formation of monolayer as well as bilayer stanene. A buffer layer -- formed due
to chemical bonding of Sn with the upper two layers of MBST (Te and Bi/Sb) --
facilitates the growth of stanene.
