A Platform for Addressing Individual Magnetite Islands Grown Epitaxially on Ru(0001) and Manipulating Their Magnetic Domains
Sandra Ruiz-Gómez, Eva María Trapero, Claudia Fernández-González +8
We have grown high-quality magnetite micrometric islands on ruthenium stripes on sapphire through a combination of magnetron sputtering (Ru film), high-temperature molecular beam e…
Tuning the Néel temperature in an antiferromagnet: the case of NixCo1-xO microstructures
Anna Mandziak, Guiomar D. Soria, José Emilio Prieto +6
We show that it is possible to tune the Néel temperature of nickel(II)-cobalt(II) oxide films by changing the Ni to Co ratio. We grow single crystalline micrometric triangular isla…
Clocked dynamics in artificial spin ice
Johannes H. Jensen, Anders Strømberg, Ida Breivik +6
Artificial spin ice (ASI) are nanomagnetic metamaterials exhibiting a wide range of emergent properties, which have recently shown promise for neuromorphic computing. However, the…
Observation and formation mechanism of 360° domain wall rings in Synthetic Anti-Ferromagnets with interlayer chiral interactions
Miguel A. Cascales Sandoval, A Hierro-Rodríguez, S. Ruiz-Gómez +10
The Interlayer Dzyaloshinskii-Moriya interaction (IL-DMI) chirally couples spins in different ferromagnetic layers of multilayer heterostructures. So far, samples with IL-DMI have…
GHz sample excitation at the ALBA-PEEM
Muhammad Waqas Khaliq, José M. Álvarez, Antonio Camps +9
We describe a setup that is used for high-frequency electrical sample excitation in a cathode lens electron microscope with the sample stage at high voltage as used in many synchro…
Determination of optimal experimental conditions for accurate 3D reconstruction of the magnetization vector via XMCD-PEEM
Miguel A. Cascales Sandoval, A. Hierro-Rodríguez, S. Ruiz-Gómez +10
In this work we present a detailed analysis on the performance of X-ray magnetic circular dichroism photo-emission electron microscopy (XMCD-PEEM) as a tool for vector reconstructi…
