Evidence of a topological Hall effect in EuSmTiO
Kaveh Ahadi, Luca Galletti, Susanne Stemmer
We report on the observation of a possible topological Hall effect in thin films of the itinerant ferromagnet Eu1-xSmxTiO3. EuTiO3 and Eu0.955Sm0.045TiO3 films were grown by molecu…
Response of the lattice across the filling-controlled Mott metal-insulator transition of a rare earth titanate
Honggyu Kim, Patrick B. Marshall, Kaveh Ahadi +3
The lattice response of a prototype Mott insulator, SmTiO3, to hole doping is investigated with atomic-scale spatial resolution. SmTiO3 films are doped with Sr on the Sm site with…
Growth of strontium ruthenate films by hybrid molecular beam epitaxy
Patrick B. Marshall, Honggyu Kim, Kaveh Ahadi +1
We report on the growth of epitaxial Sr2RuO4 films using a hybrid molecular beam epitaxy approach in which a volatile precursor containing RuO4 is used to supply ruthenium and oxyg…
Novel metal-insulator-transition at the SrTiO3/SmTiO3 interface
Kaveh Ahadi, Susanne Stemmera
We report on a metal-insulator transition (MIT) that is observed in an electron system at the SmTiO3/SrTiO3 interface. This MIT is characterized by an abrupt transition at a critic…
