Nanoscale friction of manganite superlattice films controlled by layer thickness and fluorine content
Niklas A. Weber, Miru Lee, Florian Schönewald +4
We investigate nanoscale friction in [LaMnO3]m/[SrMnO3]n superlattice films using lateral force microscopy, focusing on the effects of fluorine doping and top-layer thickness. For…
Nanoscale friction controlled by top layer thickness in [LaMnO]/[SrMnO] superlattices
Niklas A. Weber, Miru Lee, Florian Schönewald +4
We conducted lateral force microscopy measurements on seven [LaMnO]/[SrMnO] superlattices with varied layer thicknesses. We observe that the friction forces…
Friction on layered media: How deep do phonons reach?
Miru Lee, Niklas Weber, Cynthia A. Volkert +1
We theoretically study the frictional damping of a small probe object on a coated planar surface, analyzing the resulting phonon modes via a theory of viscoelasticity. Three differ…
Polaronic Contributions to Friction in a Manganite Thin Film
Niklas A. Weber, Hendrik Schmidt, Tim Sievert +6
Despite the huge importance of friction in regulating movement in all natural and technological processes, the mechanisms underlying dissipation at a sliding contact are still a ma…
Switching friction at a manganite surface using electric fields
H. Schmidt, J. -O. Krisponeit, N. Weber +2
We report active control of the friction force at the contact between a nanoscale asperity and a LaCaMnO (LCMO) thin film using electric fields. We use fricti…
