Nonvolatile spintronics-based devices that utilize electron spin both tostore and transport information face a great challenge when scaled to nanodimensions due to loss of thermal stability and stray field induced disturbancein closely packed magnetic bits. The potential replacement of ferromagneticmaterials with antiferromagnets may overcome some of these issues owing to thesuperior robustness of sublattice spin orientations to magnetic fielddisturbance as long as theyare kept well below the N\'eel temperature, which ishard to measure with conventional methods, especially in the ultrathin limit.In this work, we have employed spin pumping from a soft ferromagnetic NiFelayer into widely used ultrathin metallic antiferromagnet Ir20Mn80, FeMn, PtMn,PdMn or NiMn with thicknesses in the 0.7-3 nm range, as a probe to detectdamping enhancement during magnetic phase transitions. Independent measurementsof the blocking temperature with magnetometry reveal that temperature dependentshifts in the resonance peaks can also be used to measure the blockingtemperature, allowing the analysis of the correlation between the N\'eel andblocking temperatures in trilayers with permalloy and antiferromagnetic layerseparated by a 3 nm thick spacer layer. The thickness dependentcharacterization of thermal stability in antiferromagnets provides a keyelement for scalable and ultrafast antiferromagnetic spintronics.
