R. Jarrier,R. Jarrier,Xavier Marti,Julia Herrero-Albillos,Julia Herrero-Albillos,Pilar Ferrer,Raphael Haumont,Raphael Haumont,P. Gemeiner,Grégory Geneste,Patrick Berthet,T. Schulli,Pavel Cevc,Robert Blinc,Stanislaus S. Wong,Stanislaus S. Wong,Tae-Jin Park,Tae-Jin Park,Marin Alexe,Michael A. Carpenter,James F. Scott,Gustau Catalan,Brahim Dkhil +22 more
TL;DR: In this paper, a wide variety of experimental techniques were combined to analyze two heretofore mysterious phase transitions in multiferroic bismuth ferrite at low temperature, and the transition at $T$ $=$ 140.3 K was shown to be a surface phase transition, with an associated sharp change in lattice parameter and charge density at the surface.
Journal ArticleDOI
The Poisson Ratio in CoFe2O4 Spinel Thin Films
Michael Foerster,Michael Foerster,Milko Iliev,N. Dix,Xavier Marti,M. Barchuk,Florencio Sánchez,Josep Fontcuberta +7 more
TL;DR: In this article, the response of epitaxial CoFe2O4 thin films to biaxial compressive stress imposed by MgAl 2O4 and SrTiO3 single crystalline substrates is studied using X-ray diffraction and Raman spectroscopy.
Journal ArticleDOI
Lifting Dirac nodes in topological semimetallic perovskite SrIrO3 through epitaxial constraint
Jian Liu,Dominik Kriegner,Lukáš Horák,Danilo Puggioni,C. Rayan Serrao,Renkun Chen,Di Yi,Carlos Frontera,Vaclav Holy,Ashvin Vishwanath,James M. Rondinelli,Xavier Marti,R. Ramesh +12 more
TL;DR: In this paper, the symmetry-protected Dirac line nodes in the topological semimetallic perovskite SrIrO3 can be lifted simply by applying epitaxial constraint.
Journal ArticleDOI
Electrical measurement of antiferromagnetic moments in exchange-coupled IrMn/NiFe stacks.
Xavier Marti,Byong-Guk Park,Jörg Wunderlich,Helena Reichlova,Yosuke Kurosaki,M. Yamada,H. Yamamoto,Akinori Nishide,J. Hayakawa,Hiromasa Takahashi,Tomas Jungwirth +10 more
TL;DR: In this paper, the behavior of antiferromagnetic moments in IrMn exchange coupled to NiFe was studied and the broadening of the NiFe hysteresis loop and its shift (exchange bias) was found to correlate with the rotation and pinning of the moments inside the irMn film.
Journal ArticleDOI
Emergence of ferromagnetism in antiferromagnetic TbMnO3 by epitaxial strain
Xavier Marti,Vassil Skumryev,C. Ferrater,M.V. García-Cuenca,Maria Varela,Florencio Sánchez,Josep Fontcuberta +6 more
TL;DR: In this article, it was shown that in oxide thin films of spiral antiferromagnetic orthorhombic TbMnO3, ferromagnetism emerges resulting from epitaxially induced strain.
