Welcome to Keele Repository

The Keele Repository is intended to be an Open Access showcase for the published research output of the university. Whenever possible, refereed documents accepted for publication, or finished artistic compositions presented in public, will be made available here in full digital format, and hyperlinks to standard published versions will be provided.

Morphology and capping effects in the magnetic and magneto-optical properties of nanoparticulate Co films (2008)
Journal Article
Clavero, C., Martínez, L., García-Martín, A., García-Martín, J. M., Huttel, Y., Telling, N. D., …Armelles, G. Morphology and capping effects in the magnetic and magneto-optical properties of nanoparticulate Co films. Physical review B: Condensed matter and materials physics, 77(9), https://doi.org/10.1103/physrevb.77.094417

Magnetic and magneto-optical properties of Co films are studied as a function of the morphology and the capping layer. We show that the nanoparticulate structure of the Co films has a clear influence on the magnetic and magneto-optical properties of...

X-ray absorption and magnetic circular dichroism characterization of a novel ferromagnetic MnNx phase in Mn/Si3N4 multilayers (2008)
Journal Article
Céspedes, E., Huttel, Y., Martínez, L., de Andrés, A., Chaboy, J., Vila, M., …Prieto, C. (2008). X-ray absorption and magnetic circular dichroism characterization of a novel ferromagnetic MnNx phase in Mn/Si3N4 multilayers. Applied Physics Letters, 93(25), https://doi.org/10.1063/1.3050534

Ferromagnetism above room temperature has been observed in multilayered films for the first time. Characterization of the structural and electronic properties was performed to study the ferromagnetic behavior of this system. X-ray absorption spect...

Temperature dependence of the interface moments in Co2MnSi thin films (2008)
Journal Article
Telling, N. D., Keatley, P. S., Shelford, L. R., Arenholz, E., van der Laan, G., Hicken, R. J., …Miyazaki, T. (2008). Temperature dependence of the interface moments in Co2MnSi thin films. Applied Physics Letters, 92(19), https://doi.org/10.1063/1.2927482

X-ray magnetic circular dichroism (XMCD) is utilized to explore the temperature dependence of the interface moments in (CMS) thin films capped with aluminum. By increasing the thickness of the capping layer, we demonstrate enhanced interface sensi... Read More about Temperature dependence of the interface moments in Co2MnSi thin films.

Interface alloying effects in the magnetic properties of Fe nanoislands capped with different materials (2008)
Journal Article
Huttel, Y., Navarro, E., Telling, N. D., van der Laan, G., Pigazo, F., Palomares, F. J., …Cebollada, A. Interface alloying effects in the magnetic properties of Fe nanoislands capped with different materials. Physical review B: Condensed matter and materials physics, 78(10), https://doi.org/10.1103/physrevb.78.104403

We show that Fe nanoislands capped with Al, Pd, and Pt protecting layers include an alloy at the interface with the capping layer, which explains the previously known capping layer dependence on the interparticle magnetic coupling. Vibrating sample m... Read More about Interface alloying effects in the magnetic properties of Fe nanoislands capped with different materials.

Probing the site occupancies of Co-, Ni-, and Mn-substituted biogenic magnetite using XAS and XMCD (2008)
Journal Article
Coker, V. S., Pearce, C. I., Pattrick, R. A., van der Laan, G., Telling, N. D., Charnock, J. M., …Lloyd, J. R. (2008). Probing the site occupancies of Co-, Ni-, and Mn-substituted biogenic magnetite using XAS and XMCD. American Mineralogist, 93(7), 1119-1132. https://doi.org/10.2138/am.2008.2681

Ferrimagnetic nanoparticles have many uses in industry including in magnetic recording media and transformers, however these particles are often expensive to synthesize. In this study, the Fe3+-reducing bacteria Geobacter sulfurreducens and Shewanell... Read More about Probing the site occupancies of Co-, Ni-, and Mn-substituted biogenic magnetite using XAS and XMCD.
