Abstract: Abstract The effect of site disorder (originating from the presence of substitutional atoms) on intrinsic magnetic properties of intermetallic phases derived from the ThMn12-type crystal structure has been studied using the tight-binding linear-muffin-tin-orbital atomic-sphere approximation… read more here.

DOI: 10.1016/j.jmmm.2020.167388
Abstract: Abstract We report the effects of implantation-induced-sputtering in determining the true magnetisation of iron nitrides formed by nitrogen implantation into iron films and the changes subsequently observed in their magnetic anisotropy. Iron thin films (40… read more here.

Abstract: Sub-picosecond magnetisation manipulation via femtosecond optical pumping has attracted wide attention ever since its original discovery in 1996. However, the spatial evolution of the magnetisation is not yet well understood, in part due to the… read more here.

Abstract: We consider the probability of a magnetic nanoparticle to flip its magnetisation near the blocking temperature, and use this to develop quasi-analytic expressions for the zero-field-cooled and field-cooled magnetisation, which go beyond the usual critical… read more here.

Abstract: We report on the direct observation of spin wave and elastic wave emission from magnetic domain walls in ferromagnetic thin films. Driven by alternating homogeneous magnetic fields the magnetic domain walls act as coherent magnetisation… read more here.

DOI: 10.1103/physrevb.100.104421
Abstract: We predict magnetisation plateaux ground states for $S=1/2$ Heisenberg antiferromagnets on pyrochlore lattices by formulating arguments based on gauge and spin-parity transformations. We derive a twist operator appropriate to the pyrochlore lattice, and show that… read more here.
