Kiessig fringes are observed, confirming a high sample quality and a thin film thickness of 10 septuple layers ($\\sim$13 nm). An antiferromagnetic Bragg peak is observed at the structurally forbidden reflection, whose magnetic nature is validated by studying its temperature, energy, and polarization dependence. Through a detailed analysis, an A-type antiferromagetic order with in-plane moments is implied.
