Identifying grain boundary and intragranular pinning centres in Sm2(Co,Fe,Cu,Zr)17 permanent magnets to guide performance optimisation
Stefan Giron, Nikita Polin, Esmaeil Adabifiroozjaei +21
Permanent magnets draw their properties from a complex interplay of chemical composition and phase, each with their associated intrinsic magnetic properties. Gaining an understandi…
Off-axis electron holography for the direct visualization of perpendicular shape anisotropy in nano-scale 3D magnetic random-access-memory devices
Trevor P. Almeida, Alvaro Palomino, Steven Lequeux +5
Perpendicular shape anisotropy (PSA) and double magnetic tunnel junctions (DMTJ) offer practical solutions to downscale spin-transfer-torque Magnetic Random-Access Memory (STT-MRAM…
Direct observation of the perpendicular shape anisotropy and thermal stability of p-STT-MRAM nano-pillars
Trevor P. Almeida, Steven Lequeux, Alvaro Palomino +6
Perpendicular shape anisotropy (PSA) offers a practical solution to downscale spin-transfer torque Magnetic Random-Access Memory (STT-MRAM) beyond the sub-20 nm technology node whi…
Asymmetric Magnetic Relaxation behavior of Domains and Domain Walls Observed Through the FeRh First-Order Metamagnetic Phase Transition
Jamie R. Massey, Rowan C. Temple, Trevor P. Almeida +8
The phase coexistence present through a first-order phase transition means there will be finite regions between the two phases where the structure of the system will vary from one…
Direct visualization of the magnetostructural phase transition in nano-scale FeRh thin films using differential phase contrast imaging
Trevor P. Almeida, Damien McGrouther, Rowan Temple +5
To advance the use of thermally-activated magnetic materials in device applications it is necessary to examine their behaviour on the localised scale in operando conditions. Equi-a…
Phase domain boundary motion and memristance in gradient-doped FeRh nanopillars induced by spin injection
Rowan C. Temple, Mark C. Rosamond, Jamie R. Massey +6
The B2-ordered alloy FeRh shows a metamagnetic phase transition, transforming from antiferromagnetic (AF) to ferromagnetic (FM) order at a temperature ~K in…
Antiferromagnetic-ferromagnetic phase domain development in nanopatterned FeRh islands
R. C. Temple, T. P. Almeida, J. R. Massey +9
The antiferromagnetic to ferromagnetic phase transition in B2-ordered FeRh is imaged in laterally confined nanopatterned islands using photoemission electron microscopy with x-ray…
