We investigate the anomalous transverse conductivities of a two-dimensional (2D) magnetic Fe3GaTe2 system (monolayer to four-layer thickness). A giant anomalous thermal Hall conductivity (ATHC) of -0.14 W/K.m is obtained in the four-layer structure, and this value is comparable to the typical ATHC found in bulk materials which is rare to find in low-dimensional systems. Our findings suggest that the ultra-thin 2D Fe3GaTe2 system could be a promising platform for future spintronics and spin caloritronics device applications.
