Journal Article
Tokaç, M., Kazan, S., Özkal, B., Al-jawfi, N., Rameev, B., Nicholson, B., & Hindmarch, A. T. (2023). Two Magnon Scattering Contribution to the Ferromagnetic Resonance Linewidth of Pt(Ir)/CoFeTaB/Ir(Pt) Thin Films. Applied Magnetic Resonance, 54(10), 1053-1064. https://doi.org/10.1007/s00723-023-01601-3

The magnetic properties of Pt/CoFeTaB/Ir and Ir/CoFeTaB/Pt trilayer thin films have been studied using angular- and temperature-dependent ferromagnetic resonance. This enables quantitative determination of the various contributions to the magnetic be...

Proximity-induced magnetism in Pt layered with rare-earth–transition-metal ferrimagnetic alloys (2020)
Journal Article
Swindells, C., Nicholson, B., Inyang, O., Choi, Y., Hase, T., & Atkinson, D. (2020). Proximity-induced magnetism in Pt layered with rare-earth–transition-metal ferrimagnetic alloys. Physical Review Research, 2(3), Article 033280. https://doi.org/10.1103/physrevresearch.2.033280

The proximity-induced moment (PIM) in heavy metal layers may play a significant role in heterostructured spintronic systems. In particular, the PIM of a heavy metal adjacent to a magnetic layer has been linked to interfacial spin transport behavior....

Threshold interface magnetization required to induce magnetic proximity effect (2019)
Journal Article
Inyang, O., Bouchenoire, L., Nicholson, B., Tokaç, M., Rowan-Robinson, R., Kinane, C., & Hindmarch, A. (2019). Threshold interface magnetization required to induce magnetic proximity effect. Physical Review B, 100(17), Article 174418. https://doi.org/10.1103/physrevb.100.174418

Proximity-induced magnetization (PIM) has broad implications across interface-driven spintronics applications employing spin currents. We directly determine the scaling between PIM in Pt and the temperaturedependent interface magnetization in an adja...

The interfacial Dzyaloshinskii-Moriya interaction (IDMI) is investigated in Co2FeAl (CFA) ultrathin films of various thicknesses (0.8 nm ≤ tCFA ≤ 2nm) grown by sputtering on Si substrates, using Pt, W, Ir, and MgO buffer or/and capping layers. Vibrat... Read More about Thickness Dependence of the Dzyaloshinskii-Moriya Interaction in Co2FeAl Ultrathin Films: Effects of Annealing Temperature and Heavy-Metal Material.
