X-ray magnetic circular dichroism study of Dy-doped Bi2Te3 topological insulator thin films by Figueroa, A, Baker, A, Harrison, S, Kummer, K, van der Laan, G, Hesjedal, T

“…Here, we present a surface-sensitive x-ray magnetic circular dichroism (XMCD) study of an in situ cleaved lm in the cleanest possible environment. …”

Study of Gd-doped Bi2Te3 thin films: Molecular beam epitaxy growth and magnetic properties by Harrison, SE, Collins-McIntyre, L, Li, S, Baker, A, Shelford, L, Huo, Y, Pushp, A, Parkin, S, Harris, J, Arenholz, E, van der Laan, G, Hesjedal, T

“…Magnetometry reveals that the films are paramagnetic down to 1.5 K. X-ray magnetic circular dichroism at the Gd M4,5 edge at 1.5 K reveals a saturation field of ∼6 T, and a slow decay of the magnetic moment with temperature up to 200 K. …”

Magnetic Cr doping of Bi2Se3: Evidence for divalent Cr from x-ray spectroscopy by Figueroa, A, van der Laan, G, Collins-McIntyre, L, Zhang, S, Baker, A, Harrison, SE, Schoenherr, P, Cibin, G, Hesjedal, T

“…Comparison of the Cr L2,3 x-ray magnetic circular dichroism at T=5 K with multiplet calculations gives a spin moment of 3.64 μB/Crbulk, which is close to the saturation moment for Cr2+ d4. …”

Tailoring of magnetic anisotropy and interfacial spin dynamics by Baker, A

“…</p> <p>This thesis presents an investigation into the magnetodynamics of ferromagnetic thin films and heterostructures grown by molecular beam epitaxy and studied using vector-network analyser ferromagnetic resonance (VNA-FMR), x-ray magnetic circular dichroism, vibrating sample magnetometry and x-ray detected ferromagnetic resonance (XFMR). …”
