Direct observation of Jahn-Teller critical dynamics at a charge-order Verwey transition
Vinícius Pascotto Gastaldo, Mala N. Rao, Alexey Bosak +10
By means of diffuse and inelastic x-ray scattering (DS,IXS), we probe directly the charge-ordering (CO) dynamics in the Verwey system (NaMn)MnO, where a peculiar qua…
Enhancing the effective critical current density in a Nb superconducting thin film by cooling in an inhomogeneous magnetic field
D. A. D. Chaves, I. M. de Araújo, D. Carmo +7
Quantitative magneto-optical imaging of a type-II superconductor thin film cooled under zero, homogeneous, and inhomogeneous applied magnetic fields, indicates that the latter proc…
Unconventional magnetic ferroelectricity in the quadruple perovskite NaMnO
Vinícius Pascotto Gastaldo, Yannick Klein, Benoît Baptiste +4
By means of magnetic, specific heat and pyroelectric measurements, we report on magnetic ferroelectricity in the quadruple perovskite \namno, characterized by a canted antiferromag…
Ferroelectricity in the 1 C cm range induced by canted antiferromagnetism in (LaMn)MnO
A. Gauzzi, F. Milton, V. Pascotto Gastaldo +8
Pyroelectric current and magnetoelectric coupling measurements on polycrystalline samples of the quadruple perovskite (LaMn)MnO give evidence of ferroelectricity…
Thermal enhancement of the antiferromagnetic exchange coupling between Fe epilayers separated by a crystalline ZnSe spacer
J. Varalda, J. Milano, A. J. A. de Oliveira +8
We have put into evidence the existence of an antiferromagnetic coupling between iron epilayers separated by a ZnSe crystalline semiconductor. The effect has been observed for ZnSe…
