Abstract Magnetic and transport properties as well as magnetic domain structures have been investigated in a hexagonal polycrystalline Mn2.1Fe0.9Sn compound. The in-situ observation of Lorentz transmission electron microscopy shows that spontaneous magnetic bubbles owing a pair of Bloch lines and biskyrmions consisting of two skyrmions of opposite spin helicities coexist in this compound at low temperature. A large topological Hall resistivity up to about 9 µΩ·cm at 50 K has been found owing to the formation of noncoplanar spin textures deriving from the competition among magnetocrystalline anisotropy, antiferromagnetic coupling, and ferromagnetic interaction.
