Chiral $2\pi$-exchange NN-potentials: Two-loop contributions [PDF]
, 2001 We calculate in heavy baryon chiral perturbation theory the local NN-potentials generated by the two-pion exchange diagrams at two-loop order. We give explicit expressions for the mass-spectra (or imaginary parts) of the corresponding isoscalar and ...

Macrospin dynamics in antiferromagnets triggered by sub-20 femtosecond injection of nanomagnons
Nature Communications, 2016 Magnetic order in nature is defined by the exchange interaction, however its understanding on the ultrafast- and nanometer-scales is limited. Here, the authors follow the femtosecond sub-nanometer dynamics of the antiferromagnetic order parameter in ...

Influence of surface roughness and deposition order on exchange bias in bilayer structures NiFe/IrMn
EPJ Web of Conferences, 2014 Using ferromagnetic resonance (FMR) method, magnetic properties of bilayer structures consisting of ferromagnetic (F, Ni80Fe20) and antiferromagnetic (AF, Ir25Mn75) layers with alternative order of F and AF deposition were studied.
