Work programme

This comprises a comprehensive growth campaign providing materials for all the experimental work packages (WP 3, 4, 5). The campaign will use an iterative process of growth, characterisation (WP3) and atomistic calculations of WP2 to optimise materials. Progress in WP1 will be informed by results in WPs 4-5 and feed into WP3.
Increased impact (WP6) will follow through the provision of world class materials to collaborators.

The WP lead is Oscar Céspedes, University of Leeds.

This work package develops a multiscale approach propagating calculations from first principles up to device scale simulations including fundamental properties of antiferromagnets (AFMs) (WP 1, 4), magnetostriction, simulations of switching rates and switching probabilities in different materials (WP5), and thermal diffusion constants of skyrmions (WP 4,5).
We will study defects, amorphous and perfect systems in thin films that affect magnetism (WP3, 5), spin textures (WP4) and thermodynamics (WP5) with calculations of exchange stiffness and (DMI) (WP 3,5).

The WP lead is Joseph Barker, University of Leeds.

This work package will deliver new ways of using spin-based entities that could convey information targeting low-power consumption. We will explore the pinning control of AFM materials, guided by calculations from WP2 and interface characterisation from WP3, to understand the motion of ferromagnetic domain walls. Ferroelectric domain wall motion will be controlled by molecules, drawing on the work in WP3, to create 2D conductors and dynamic 1D p-n junctions. The topological materials from WP1 will be focused on the development of high mobility protected states to produce surface conducting spin currents, e.g. tuned by molecules, where forming interconnections is the work of WP3 and spin-torque in WP5.
The WP lead is Marty Gregg, Queen's University Belfast.

Central to the operation of magnetic elements is the switching of magnetic moments to represent the storage of digital bits. We will exploit the influence that molecules can exert on ferroelectric domains (WP1, WP3) to achieve switching, and for ferromagnetic domains we will use supercurrents (WP4, 5). Giant spin orbit torques from TIs will follow on from WP3. We will modulate AFM order by the application of voltage-controlled stress and use molecular-metal-oxides to enhance/control spin-orbit effects and spin textures (WP3).

This work package will ensure the delivery of (i) ECR career development, (ii) Academic impact, (iii) Programme synergy, (iv) Industrial engagement, (v) Outreach and (vi) Advocacy.
The WP lead is Andrew Bell.
