Anthony Schuyler Arrott (born April 1, 1928) was an American-born Canadian physicist, and a professor at Carnegie Institute of Technology and Simon Fraser University. He was a specialist in condensed matter physics, the physics of magnetism, and liquid crystals. He was the author of over 200 scientific papers.[1] Arrott is the subject of the 2020 documentary Portrait, directed by Lily Ekimian and A.T. Ragheb.[2]

Early work

Arrott wrote his PhD thesis at the Carnegie Institute of Technology on the magnetic properties of Nickel alloys.[3]

After working at Carnegie Tech from 1953 to 1956, he joined the physics department of the Ford Scientific Laboratory in Dearborn, Michigan, where he studied the magnetic properties of iron alloys.[4]

Research area

In 1957, he suggested a straightforward criterion for ferromagnetism from observations of magnetic isotherms.[5] This method was called Arrott plots.[6][7] In collaboration with Murray J. Press, he gave a description of surface singularities in liquid-crystal droplets.[8] A lot of works are devoted to the properties of ferromagnetic samples (for example the so-called Arrott's cylinder[9]) with micrometer and sub-micrometer sizes.[10][11][12] Commissioned in 1978, Arrott designed the Thermal Neutron Facility at the TRIUMF cyclotron.[1]
