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…
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…
