Change of surface critical current in the surface superconductivity and mixed states of superconducting Niobium
Muhamad Aburas, Alain Pautrat, Natalia Bellido
A systematic study of irreversible magnetization was performed in bulk Niobium after different surface treatments. Starting with smooth surfaces and abrading them, a strong increas…
Analysis of the multiferroicity in the hexagonal manganite YMnO3
Kiran Singh, Marie-Bernadette Lepetit, Charles Simon +4
We performed magnetic and ferroelectric measurements, associated with Landau theory and symmetry analysis, in order to clarify the situation of the YMnO3 system, a classical exampl…
Role of the ferromagnetic component in the ferroelectricity of YMnO3
Kiran Singh, Natalia Bellido, Charles Simon +4
We performed magnetic and ferroelectric measurements, first principle calculations and Landau theory analysis on hexagonal YMnO3. The polarization and the AFM order parameter were…
Direct correlation between strengthening mechanisms and electrical noise in strained copper wires
Natalia Bellido, Alain Pautrat, Clement Keller +1
We have measured the resistance noise of copper metallic wires during a tensile stress. The time variation of the main resistance is continuous up to the wire breakdown, but its fl…
Anomaly in Nonlinear Magnetoelectric Response of YbMnO3
U. Adem, M. Mostovoy, N. Bellido +3
We observe a seemingly complex magnetic field dependence of dielectric constant of hexagonal YbMnO3 near the spin ordering temperature. After rescaling, the data taken at different…
Magnetodielectric coupling in a triangular Ising lattice
Natalia Bellido, Charles Simon, Antoine Maignan
Dielectric constant measurement under magnetic field is an efficient technique to study the coupling between charges and spins in insulating materials. For magnetic oxides, the geo…
