Magnetic relaxation in large spin molecular paramagnets is often found to behave as δM(t) ∼ √ t at short times t. This behaviour was explained by Prokofiev & Stamp as arising from dipole interactions between molecular spins. However, as observed by Miyashita & Saito, the same behaviour can arise from a different mechanism which, in the present work, is related to hyperfine interactions. The Miy...

We have determined the magnetic structure of the Fe sublattice in YFe6Ge6 by highresolution neutron powder diffraction. The crystal space group is Cmcm and the magnetic space group is CPm′c′m′. The Fe modes are GX , G − X and G − X at the 8d, 8e and 8g sites, respectively. The easy direction of magnetization is [100] and the propagation vector is [010].

for an Invited Paper for the MAR11 Meeting of The American Physical Society Ultrafast magnetization dynamics in a system with tunable angular momentum ANDREI KIRILYUK, Radboud University Nijmegen Many peculiarities of the magnetization dynamics are related to the fact that a certain amount of angular momentum is associated with magnetic moment. Here the dynamics of angular momentum is studied i...

We discuss the effects of thermal noise on magnetic response a lateral ferromagnetic Josephson junction with spin-orbit coupling and out-of-plane magnetization. The direction moment in layer can be inverted by using controlled current pulses. This phenomenon is due to magnetoelectric effect that couples flowing charge magnetization ferromagnet. investigate reversal versus intrinsic parameters f...

Abstract Kramers Weyl semimetals are that have points pinned at the time reversal invariant momenta. Recently it has been discovered all chiral crystals host momenta, so metals with lattice symmetry belong to category of semimetals. In this work, we show due symmetry, unique longitudinal magnetoelectric effect in which charge current induced spin and orbital magnetization is parallel direction ...
