Electric modulation of conduction in multiferroic Ca-doped BiFeO3 films
Chan-Ho Yang,Jan Seidel,Jan Seidel,Sang-Yong Kim,P. B. Rossen,Pu Yu,M. Gajek,Ying-Hao Chu,Lane W. Martin,Lane W. Martin,Mikel B. Holcomb,Mikel B. Holcomb,Qing He,Petro Maksymovych,Nina Balke,Nina Balke,Sergei V. Kalinin,Arthur P. Baddorf,S. R. Basu,Matthew L. Scullin,Ramamoorthy Ramesh,Ramamoorthy Ramesh +21 more
TL;DR: The observation of an electronic conductor-insulator transition by control of band-filling in the model antiferromagnetic ferroelectric BiFeO3 through Ca doping opens the door to merging magnetoelectrics and Magnetoelectronics at room temperature by combining electronic conduction with electric and magnetic degrees of freedom already present in the multiferroic Bi FeO3.
Journal ArticleDOI
Polarization Control of Electron Tunneling into Ferroelectric Surfaces
Peter Maksymovych,Stephen Jesse,Pu Yu,Ramamoorthy Ramesh,Arthur P. Baddorf,Sergei V. Kalinin +5 more
TL;DR: It is shown that the tip of an atomic force microscope can be used to pattern polarization domains in a thin film of lead zirconate titanate in high electric fields similar to those for field emission tips.
Journal ArticleDOI
The band excitation method in scanning probe microscopy for rapid mapping of energy dissipation on the nanoscale
TL;DR: In this article, the authors developed a band excitation (BE) SPM, which allows very rapid acquisition of the full frequency response at each point (i.e. transfer function) in an image and in particular enables the direct measurement of energy dissipation through the determination of the Q-factor of the cantilever-sample system.
Journal ArticleDOI
Switching spectroscopy piezoresponse force microscopy of ferroelectric materials
TL;DR: In this paper, the authors introduce switching spectroscopy piezoresponse force microscopy as a tool for real-space imaging of switching properties on the nanoscale, including imprinting, coercive bias, remanent and saturation responses.
Journal ArticleDOI
Domain wall conductivity in La-doped BiFeO3
Jan Seidel,Jan Seidel,Petro Maksymovych,Y Batra,Allard J. Katan,S. Y. Yang,Qing He,Arthur P. Baddorf,Sergei V. Kalinin,Chan-Ho Yang,Jan Chi Yang,Ying-Hao Chu,Ekhard K. H. Salje,Ekhard K. H. Salje,Herbert Wormeester,Miquel Salmeron,Ramamoorthy Ramesh,Ramamoorthy Ramesh +17 more
TL;DR: Nanoscale current measurements are investigated as a function of bias and temperature and are shown to be consistent with distinct electronic properties at the domain walls leading to changes in the observed local conductivity.
