  The photoinduced topological phase transitions and thermal Hall conductivity
of a kagome magnet with Heisenberg, Kitaev, and DM interactions under an
external magnetic field aligned along the [111] directions is investigated in
this study. In the presence of a strong magnetic field perpendicular to the
lattice plane in the [111] direction, the system exhibits a fully polarized
paramagnetic phase and the magnon band carries an asymmetric Chern number
across the phase diagram region. Utilizing magnetic Floquet-Bloch theory, we
demonstrate that periodically driven intrinsic topological magnetic materials
can be manipulated into different topological phases with varying Berry
curvature, Chern numbers and thermal Hall conductivities signatures by
adjusting light intensity throughout the phase diagram region.
