Ramsay A, Roy P, Haigh J, Otxoa R, Irvine A, Janda T, et al.
Phys Rev Lett . 2015 Feb; 114(6):067202. PMID: 25723242
We demonstrate optical manipulation of the position of a domain wall in a dilute magnetic semiconductor, GaMnAsP. Two main contributions are identified. First, photocarrier spin exerts a spin-transfer torque on...

Surg Radiol Anat . 1990 Jan; 12(1):31-6. PMID: 2345894
The study of the spaces between the metacarpal heads on 23 cadavers, raises the question of the existence of bursae at this level. This is in line with recent studies...
