  "abstract": "We report on the longitudinal magnetoresistance (MR) in thin metal films on an Ising-type antiferromagnetic insulator, \\ce{Na_5Co_{15.5}Te_6O_{36}} (\\ce{NCTO}). Steep changes in the MR spectra with hysteresis were observed at spin-flip transitions driven by magnetic fields applied along the easy axis of the \\ce{NCTO} crystal. The MR jumps almost follow step-like changes in magnetization at the spin-flip transition. At very low temperatures where \\ce{Co} moments are partially frozen, the MR anomalies exhibit a tunnel-magnetoresistance-like shape. The observed MR anomalies at the spin-flip transition are attributed to strain effects via magnetostriction upon the magnetic-structure change of the \\ce{Co} nets in \\ce{NCTO}, because similar MR jumps are observed in \\ce{Pt/NCTO}, \\ce{Pt/SiO_x/NCTO}, and \\ce{Cu/NCTO} heterostructures. Interestingly, we found that the high-field slopes of the MR spectra show opposite signs between \\ce{Pt/NCTO} and \\ce{Cu/NCTO} at low temperatures. Because similar MR spectra are observed for \\ce{Pt/SiO_x/NCTO} in which the interface magnetic interaction is negligible, the weak antilocalization due to the strong spin-orbit interaction of the Pt films is likely to contribute to the low-temperature MR.",
