Domain Wall Propagation and Pinning Induced by Current Pulses in Cylindrical Modulated Nanowires
C. Bran, J. A. Fernandez-Roldan, J. A. Moreno +11
The future developments of three-dimensional magnetic nanotechnology require the control of domain wall dynamics by means of current pulses. While this has been extensively studied…
High power density energy harvesting devices based on the anomalous Nernst effect of Co/Pt magnetic multilayers
Guillermo Lopez-Polin, Hugo Aramberri, Jorge Marques-Marchan +4
The anomalous Nernst effect (ANE) is a thermomagnetic phenomenon with potential applications in thermal energy harvesting. While many recent works studied the approaches to increas…
Observation of hedgehog skyrmions in sub-100 nm soft magnetic nanodots
Eider Berganza, Miriam Jaafar, Maite Goiriena-Goikoetxea +7
Magnetic skyrmions are nanometric spin textures of outstanding potential for spintronic applications due to unique features governed by their non-trivial topology. It is well known…
Direct Observation of Transverse and Vortex Metastable Magnetic Domains observed in Cylindrical Nanowires
C. Bran, J. A. Fernandez-Roldan, E. M. Palmero +9
We present experimental evidence of metastable magnetic domains in cylindrical CoNi nanowires. Transverse (perpendicular) domains have been previously observed only in flat nanostr…
Domain wall pinning in FeCoCu bamboo-like nanowires
Eider Berganza, Cristina Bran, Manuel Vazquez +1
The pinning effect of the periodic diameter modulations on the domain wall propagation in FeCoCu individual nanowires is determined by Magnetic Force Microscopy, MFM. A main bistab…
An upper bound for the magnetic force gradient in graphite
David Martinez-Martin, Miriam Jaafar, Ruben Perez +2
Cervenka et al. have recently reported ferromagnetism along graphite steps. We present Magnetic Force microscopy (MFM) data showing that the signal along the steps is independent o…
Remanence of Ni nanowire arrays: Influence of size and labyrinth magnetic structure
J. Escrig, D Altbir, M. Jaafar +3
The influence of the macroscopic size of the Ni nanowire array system on their remanence state has been investigated. A simple magnetic phenomenological model has been developed to…
