Autor: Agrestini, S., Borgatti, F., Florio, P., Frassineti, J., Mosca, D. Fiore, Faure, Q., Detlefs, B., Sahle, C. J., Francoual, S., Choi, J., Garcia-Fernandez, M., Zhou, K. -J., Mitrovic, V. F., Woodward, P. M., Ghiringhelli, G., Franchini, C., Boscherini, F., Sanna, S., Sala, and M. Moretti

Publikováno v: Phys. Rev. Lett. 133, 066501 (2024)

A supposedly nonmagnetic 5d$^1$ double perosvkite oxide is investigated by a combination of spectroscopic and theoretical methods, namely resonant inelastic X-ray scattering, X-ray absorption spectroscopy, magnetic circular dichroism, and multiplet l

Revisiting the origin of satellites in core level photoemission of transparent conducting oxides: the case of $n$-doped SnO$_2$

Autor: Borgatti, F., Berger, J. A., Céolin, D., Zhou, J. S., Kas, J. J., Guzzo, M., McConville, C. F., Offi, F., Panaccione, G., Regoutz, A., Payne, D. J., Rueff, J. -P., Bierwagen, O., White, M. E., Speck, J. S., Gatti, M., Egdell, R. G.

Publikováno v: Phys. Rev. B 97, 155102 (2018)

The longstanding problem of interpretation of satellite structures in core level photoemission spectra of metallic systems with a low density of conduction electrons is addressed using the specific example of Sb-doped SnO$_2$. Comparison of {\it ab i

Anisotropy in c-oriented MgB2 thin films grown by Pulsed Laser Deposition

Autor: Ferdeghini, C., Ferrando, V., Grassano, G., Ramadan, W., Bellingeri, E., Braccini, V., Marre, D., Putti, M., Manfrinetti, P., Palenzona, A., Borgatti, F., Felici, R., Aruta, C.

Publikováno v: Physica C 378-381 (2002) 56

The electronic anisotropy in MgB2, is still a not completely clear topic; high quality c-oriented films are suitable systems to investigate this property. In this work we present our results on MgB2 superconducting thin films grown on MgO and sapphir

Report

Growth of c-oriented MgB2 thin films by Pulsed Laser Deposition: structural characterization and electronic anisotropy

Autor: Ferdeghini, C., Ferrando, V., Grassano, G., Ramadan, W., Bellingeri, E., Braccini, V., Marre', D., Manfrinetti, P., Palenzona, A., Borgatti, F., Felici, R., Lee, T. -L.

MgB2 thin films were deposited using Pulsed Laser Deposition (PLD) and ex-situ annealing in Mg atmosphere. The films presented critical temperatures up to 36K and turned out to be preferentially c-oriented both on Al2O3 (r-cut) and MgO(100) substrate
