New Emerging Spintronics

The group is focused on novel spintronics phenomena such as antiferromagnetic spintronics, neuromorphic computing, altermagnetism, goniopolarity or the emerging orbitronic field.

-       General objectives:

o            Realization of artificial integrated neuronal and synapse network. The aim is to develop a new hybrid system composed by an Insulator-to-Metal-Transition (IMT) CO neuron and a SAF synapses. We will combine the spiking behavior of vanadates (as VO2, V2O3) and tune the magnetic coupling with the adjacent magnetic layer to make an integrated neuron and synapse system.

o            Development of bulk-AFM materials combined with large SOC materials such as HM. We will resort to spin-orbit interfacial phenomena generated at the interface to manipulate spins for neuromorphic computing or terahertz emission purposes. With external fields or applied currents we will finely tune AFM switching, nucleation and motion of DWs and AFM skyrmions, or exchange bias.

o            Experimental development of the new field called Altermagnetism, which consists of a new type of magnetism. Electronic and structural characterization and transport measurements will be performed on oxide or fluoride materials.

o            Starting the investigation of the new emergent field of goniopolar materials in thin films, which is a gap in the field. Goniopolar materials are those that in orthogonal preferred orientations and under the effect of electric fields can doped with electrons or holes respectively. The combination of goniopolar materials with others in which the doping effect is crucial, can open the pathway to new physics and properties.

o            Orbital DMI. The last line of research to be developed is oriented towards the new field of orbitronics focused on the Dzyaloshinskii-Moriya interaction. In parallel with the phenomena occurring in spins, orbital interactions open a path where it is possible to stabilize and manipulate topological or chiral objects by combining materials with different orbital hybridizations.
