Michael Coey

John Michael David Coey (24 February 1945 – 6 October 2025), known as Michael Coey, was a Northern Irish-born experimental physicist working in the fields of magnetism and spintronics. He was a professor at the Trinity College Dublin (TCD).

Life and career

Education Michael Coey completed a BA in Physics at Jesus College, Cambridge in 1966; he then travelled across Europe and Asia, teaching English and Physics in India.

He was at the physics department of Trinity College Dublin (TCD) from 1978. He obtained his ScD in 1987 and passed his Habilitation from the University of Grenoble in 1986, and an honorary doctorate in 1994. He served as Erasmus Smith's Professor of Natural and Experimental Philosophy at TCD from 2007 to 2012. After retirement, he was an Emeritus professor at TCD.

Career Coey was a Professor of Physics at TCD from 1987, and was appointed Erasmus Smith's Professor of Natural and Experimental Philosophy (2007–2012), a chair that dates from 1724.

In 1994 Coey founded Magnetic Solutions and went on to be the cofounder of CRANN Ireland's Nanoscience Research institute (2002) and conceived Dublin's unique Science Gallery (2006). has been well received.

He delivered a public lecture on the History of Magnetism in Paris in 2010. He held positions at National University Singapore and the Max Planck Institute for Chemical Physics of Solids in Dresden. He also worked with Beihang University in Beijing for five years.

He was part of numerous collaborations including: IBM Yorktown Heights (1979), Institute of Physics Peking (1980), McGill University (1982), University of Bordeaux (1984), CEN-Grenoble (1985), Johns Hopkins APL (1986), Universite de Paris IV (1992), University of California, San Diego (1997), Florida State University (1998), University of Paris XI (1998), Leman University Geneva (2001/3), University of Strasbourg (2006).

Coey pioneered a co-operation project between academic and industrial laboratories in the Concerted European Action on Magnets (1985–95).

Personal life and death Coey was married to poet Wong May Coey in 1973 and had two sons.

Coey died on 6 October 2025, at the age of 80.
