Abstract
Quantum tunneling of the magnetic moments of Ni nanoparticles with various spatial atomic structures is studied. The crossover temperature of the nanoparticle fluctuations exhibits a step when the icosahedral structure of the particles changes to the fcc structure. The rate of quantum magnetic fluctuations is determined.
