The spin and lattice dynamics of a ferromagnetic nanoparticle are studied via molecular with semi-classical simulations where degrees freedom coupled dynamic uniaxial anisotropy term. We show that this model conserves total angular momentum, whereas momentum not conserved. carry out the Einstein–de Haas effect for Fe nanocluster more than 500 atoms is free to rotate, using modified version open-source spin-lattice code (SPILADY). rate transfer between proportional strength magnetic interaction. addition allows full relaxation be achieved on previously reported timescales ∼100 ps tight-binding energies comparable those small nanoclusters.
