Research Summary

My full publication list can be found here Google Scholar

My research interests include the electrical control and imaging of antiferromagnetic, altermagnetic and nodal fully compensated magnetic order.

Research highlights include the first direct demonstration of the spin split nature of altermagnetic order (J. Krempaský, P. Wadley et al - Nature volume 626, 517-522 (2024) - https://doi.org/10.1038/s41586-023-06907-7)

Unique imaging and control of altermagnets (O. J. Amin...., P. Wadley - Nature (in-press) https://doi.org/10.48550/arXiv.2405.02409

Accepted (30/09/2024) - in press Nature

This project utilised the unique properties of altermagnets to pioneer a new way of imaging and controlling altermagnetism. Accepted for publication in Nature and will be featured in a forthcoming Financial Times article.

2. Altermagnetic lifting of Kramers spin degeneracy

Nature volume 626, 517-522 (2024).

https://doi.org/10.1038/s41586-023-06907-7

The first direct experimental evidence of the spin split nature of the altermagnetic band structure. Currently in the top 0.1% of most cited articles in Physics.

3. Electrical switching of an antiferromagnet*

P. Wadley, B. Howells, J. Železný, C. Andrews, V. Hills, R. P. Campion, V. Novák, K. Olejník, F. Maccherozzi, S. S. Dhesi, S. Y. Martin, T. Wagner, J. Wunderlich, F. Freimuth, Y. Mokrousov, J.

Science 351, 6273, 587 (2016).

DOI: 10.1126/science.aab1031

(See also perspective article in the same issue - Marrows "Addressing an antiferromagnetic memory")

First demonstration that antiferromagnetic order can be efficiently and reversibly controlled using ordinary electrical currents, completely transforming the field of AF spintronics.

4. Antiferromagnetic half-skyrmions electrically generated and controlled at room temperature

OJ Amin, SF Poole, S Reimers, LX Barton, A Dal Din, F Maccherozzi, SS Dhesi, V Novák, F Krizek, JS Chauhan, RP Campion, AW Rushforth, T Jungwirth, OA Tretiakov, KW Edmonds, P. Wadley Nature Nanotechnology 18, 849-853 (2023) (https://www.nature.com/articles/s41565-023-01386-3)

I led and designed this project showing the first electrical generation and control of tiny "swirling knots", half-skyrmions, in the magnetic order of an antiferromagnet. Predicted to be a highly promising route forward for low-loss, ultrafast memory devices and a highly significant step towards application.

5. Current polarity dependent manipulation of antiferromagnetic domains Wadley P, Reimers S, Grzybowski MJ, Andrews C, Wang M, Chauhan JS, Gallagher BL, Campion RP, Edmonds KW, Dhesi SS, Maccherozzi F, Novak V, Wunderlich J and Jungwirth T.

This is the first demonstration of a two-terminal means of controlling antiferromagnetic order. This has significant impact for technology because it reduces the footprint of each device allowing higher component density. I was the main contributor, lead and corresponding author for this work.
