8 p, 554.4 KB Proof of the elusive high-temperature incommensurate phase in CuO by spherical neutron polarimetry / Qureshi, Navid (Institut Laue Langevin) ; Ressouche, Eric (Université Grenoble Alpes) ; Mukhin, Alexander (Prokhorov General Physics Institute) ; Gospodinov, Marin (Bulgarian Academy of Sciences. Institute of Solid State Physics) ; Skumryev, Vassil (Universitat Autònoma de Barcelona. Departament de Física)
After three decades of research on CuO, the AF3 phase is proven by neutrons, which clears up the mystery of symmetry-broken phases. CuO is the only known binary multiferroic compound, and due to its high transition temperature into the multiferroic state, it has been extensively studied. [...]

12 p, 487.8 KB Fingerprints of inelastic transport at the surface of the topological insulator Bi 2 Se 3 : role of electron-phonon coupling / Costache, Marius Vasile (Institut Català de Nanociència i Nanotecnologia) ; Neumann, Ingmar (Institut Català de Nanociència i Nanotecnologia) ; Sierra, Juan F. (Institut Català de Nanociència i Nanotecnologia) ; Marinova, Vera (Bulgarian Academy of Sciences. Institute of Optical Materials and Technologies) ; Gospodinov, M. M. (Bulgarian Academy of Sciences. Institute of Solid State Physics) ; Roche, Stephan (Institut Català de Nanociència i Nanotecnologia) ; Valenzuela, Sergio O. (Institut Català de Nanociència i Nanotecnologia)
We report on electric-field and temperature-dependent transport measurements in exfoliated thin crystals of the Bi2Se3 topological insulator. At low temperatures (<50 K) and when the chemical potential lies inside the bulk gap, the crystal resistivity is strongly temperature dependent, reflecting inelastic scattering due to the thermal activation of optical phonons. [...]

8 p, 1.3 MB Magnetoelectric effect and phase transitions in CuO in external magnetic fields / Wang, Zhaosheng (Helmholtz-Zentrum Dresden-Rossendorf) ; Qureshi, Navid (Institut Laue Langevin) ; Yasin, Shadi (Helmholtz-Zentrum Dresden-Rossendorf) ; Mukhin, Alexander (Institut obshcheĭ fiziki im. A.M. Prokhorova) ; Ressouche, Eric (Institute for Nanoscience and Cryogenics.

Institute of Solid State Physics) ; Skumryev, Vassil (Universitat Autònoma de Barcelona. Departament de Física)
Apart from being so far the only known binary multiferroic compound, CuO has a much higher transition temperature into the multiferroic state, 230 K, than any other known material in which the electric polarization is induced by spontaneous magnetic order, typically lower than 100 K. [...]

4 p, 1.0 MB Magnetic frustration in an iron-based Cairo pentagonal lattice / Ressouche, Eric (Commissariat à l'Énergie Atomique et aux Énergies Alternatives (França)) ; Simonet, V. (Institut Néel (Grenoble, França)) ; Canals, B. (Institut Néel (Grenoble, França)) ; Gospodinov, M. (Bulgarian Academy of Sciences. Institute of Solid State Physics) ; Skumryev, Vassil (Universitat Autònoma de Barcelona. Departament de Física) ; American Physical Society
The Fe3+ lattice in the Bi2Fe4O9 compound is found to materialize the first analogue of a magnetic pentagonal lattice. Because of its odd number of bonds per elemental brick, this lattice, subject to first neighbor antiferromagnetic interactions, is prone to geometric frustration. [...]

Texas Center for Superconductivity) ; Hadjiev, V. G. (University of Houston. Texas Center for Superconductivity) ; Gospodinov, M.

Departament de Física) ; Ressouche, Eric (Commissariat à l'Énergie Atomique et aux Énergies Alternatives (França))
The phonon structure of antiferromagnetic Bi2Fe4O9 (space group Pbnm No. 55, TN≈240  K) was studied theoretically by calculations of lattice dynamics and experimentally between 10 and 300 K by polarized Raman spectroscopy. [...]

4 p, 421.2 KB Magnetization reversal by electric-field decoupling of magnetic and ferroelectric domain walls in multiferroic-based heterostructures / Skumryev, Vassil (Universitat Autònoma de Barcelona. Departament de Física) ; Laukhin, Vladimir (Institut de Ciència de Materials de Barcelona) ; Fina, Ignasi (Institut de Ciència de Materials de Barcelona) ; Martí Rovirosa, Xavier (Institut de Ciència de Materials de Barcelona) ; Sánchez Barrera, Florencio (Institut de Ciència de Materials de Barcelona) ; Gospodinov, M. (Institut po fizika na tvŭrdoto ti︠a︡lo (Bŭlgarska akademii︠a︡ na naukite)) ; Fontcuberta, Josep (Institut de Ciència de Materials de Barcelona) ; American Physical Society
We demonstrate that the magnetization of a ferromagnet in contact with an antiferromagnetic multi-ferroic(LuMnO3)can be speedily reversed by electric-field pulsing, and the sign of the magnetic exchange bias can switch and recover isothermally. [...]
