Abstract

The combination of antiferromagnetism and topological properties in Mn <subscript>3</subscript> X (X = Sn,Ge,Ga) offers a unique platform to explore novel spin-dependent phenomena and develop innovative spintronic devices. Here, we have systematically investigated the phase transition of Mn <subscript>3</subscript> Ga thin films on SiO <subscript>2</subscript> (001)/Si substrates under various growth parameters such as seeding layer structure, annealing conditions, and film thickness. The relatively thick Mn <subscript>3</subscript> Ga films grown with Ru seeding exhibit a variety of polycrystalline hexagonal phases, including (002), and (201). The addition of a Ta layer to the conventional Ru seeding layer promotes the formation of nearly single-crystal antiferromagnetic (AF) Mn <subscript>3</subscript> Ga(002) phase from the relatively thin Mn <subscript>3</subscript> Ga films after annealing at 773 K. The investigation of the growth mechanism of Mn <subscript>3</subscript> Ga polycrystalline thin films provides a reference strategy for exploring Mn-based AF spintronic devices.<br /> (© 2024 IOP Publishing Ltd.
