Tribological aspects of Ba(Fe 0.974 Mn 0.026 ) 2 As 2 single crystals were analyzed through nanoscratch tests and correlated with fracture toughness data. The ~100µm thick samples present ab-planes stacked by following the c-axis (lamellar structure). Scratch hardness (0.31GPa for ab-plane and 2.10GPa for a(b)c-plane) and wear rate are in accordance with previous results...
Tribological properties of highly oriented lamellar FeSe 0.5 Te 0.5 superconductor samples were investigated. Nanoscratch morphologies and profiles were characterized by instrumented indentation, SEM and AFM. Anisotropies of the scratch morphologies of the ab- and a(b)c-planes were observed. Plowing seems to be the main mechanism of scratch deformation in the ab-plane, with plenty...
