Metastability in individual magnetic vortices
D. García-Pons, J. Pérez-Bailón, A. Méndiz +6
Magnetic nanoparticles play a crucial role in different fields such as biomedicine or information and quantum technologies. These applications require nanoparticles with a single,…
Scanning spin probe based on magnonic vortex quantum cavities
Carlos A. González-Gutiérrez, David García-Pons, David Zueco +1
Performing nanoscale scanning electron paramagnetic resonance (EPR) requires three essential ingredients. First, a static magnetic field together to field gradients to Zeeman split…
Measuring the magnon-photon coupling in shaped ferromagnets: tuning of the resonance frequency
Sergio Martinez-Losa del Rincon, Ignacio Gimeno, Jorge Perez-Bailon +4
Cavity photons and ferromagnetic spins excitations can exchange information coherently in hybrid architectures, at speeds set by their mutual coupling strength. Speed enhancement i…
Rectification of electronic heat current by a hybrid thermal diode
M. J. Martínez-Pérez, A. Fornieri, F. Giazotto
We report the realization of an ultra-efficient low-temperature hybrid heat current rectifier, thermal counterpart of the well-known electric diode. Our design is based on a tunnel…
Coherent diffraction of thermal currents in Josephson tunnel junctions
F. Giazotto, M. J. Martinez-Perez, P. Solinas
We theoretically investigate heat transport in temperature-biased Josephson tunnel junctions in the presence of an in-plane magnetic field. In full analogy with the Josephson criti…
Coupling single molecule magnets to quantum circuits
M. D. Jenkins, T. Hümmer, M. J. Martínez-Pérez +3
In this work we study theoretically the coupling of single molecule magnets (SMMs) to a variety of quantum circuits, including microwave resonators with and without constrictions a…
The Josephson heat interferometer
F. Giazotto, M. J. Martinez-Perez
The Josephson effect represents perhaps the prototype of macroscopic phase coherence and is at the basis of the most widespread interferometer, i.e., the superconducting quantum in…
Phase-controlled superconducting heat-flux quantum modulator
F. Giazotto, M. J. Martinez-Perez
We theoretically put forward the concept of a phase-controlled superconducting heat-flux quantum modulator. Its operation relies on phase-dependent heat current predicted to occur…
Molecular prototypes for spin-based CNOT quantum gates
F. Luis, A. Repollés, M. J. Martínez-Pérez +8
We show that a chemically engineered structural asymmetry in [Tb2] molecular clusters renders the two weakly coupled Tb3+ spin qubits magnetically inequivalent. The magnetic energy…
Ac magnetic susceptibility of a molecular magnet submonolayer directly patterned onto a microSQUID sensor
M. J. Martínez-Pérez, E. Bellido, R. de Miguel +7
We report the controlled integration, via Dip Pen Nanolithography, of monolayer dots of ferritin-based CoO nanoparticles (12 Bohr magnetons) into the most sensitive areas of a micr…
