Anisotropic magnetoresistance in antiferromagnetic kagome metal GdTi3Bi4

We reported the experimental investigation of magnetic kagome metal GdTi3Bi4 single crystals by detailed magnetic and magnetotransport measurements. The crystal shows an antiferromagnetic ordering at TN = 13 K and magnetization plateau at low temperatures. The magnetoresistance (MR) exhibits strong anisotropy when the magnetic field applied along different crystal directions. The angular-dependent MR under magnetic fields shows that the anisotropy involves with magnetic field strength and crystal orientation. Our results supply useful information for exploring the interplay between crystal structure and magnetic order in magnetic kagome metal.
