We explore how crystal orientation affects the magnetic domains in the skyrmion-hosting MnNiGa magnets by Lorentz transmission electron microscopy. As a result, we found that the formation of topological spin textures depended significantly on both the crystal orientation and magnetic field. When the magnetic field was slightly tilted 5° from the easy-axis [001], the topological trivial bubbles were observed, while in a large tilted angle of 31° from the [001] direction, the magnetic biskyrmions were observed. Our results indicate that the magnetic domains are very sensitive to the orientation of the magnetic field with respect to the easy-axis in the centrosymmetric skyrmion-hosting magnets.
