Six-fold configurational anisotropy and magnetic reversal in nanoscale Permalloy triangles (2009)
Thevenard, Laura, Petit, Dorothee, Zeng, Huang T., Cowburn, Russell P.
Six-fold configurational anisotropy was studied in Permalloy triangles, in which the shape symmetry order yields two energetically non-degenerate micromagnetic configurations of the spins, the...
Petit, Dorothee, Jausovec, Ana-Vanessa, Read, Dan, Cowburn, Russell P.
The potential experienced by transverse domain walls (TDWs) in the vicinity of asymmetric constrictions or protrusions in thin Permalloy nanowires is probed using spatially resolved magneto-optical...
Ordering in Heisenberg Spin Glasses (2007)
Petit, Dorothee, Fruchter, L., Campbell, I. A.
For five different Heisenberg spin glass systems, torque experiments were performed in applied magnetic fields up to $4 T$. The Dzyaloshinski-Moriya random anisotropy strengths, the in-field torque...
