Intrinsic properties of magnetic nanoparticles are reviewed, with special emphasis on the
effects of finite size on zero-temperature spin ordering, magnetic excitations, and relaxation …

We report the observation of steps at regular intervals of magnetic field in the hysteresis loop
of a macroscopic sample of oriented M n 12 O 12 (CH 3 COO) 16 (H 2 O) 4 crystals. The …

We present a method for atomic-scale modeling of the magnetic behavior of ionic magnetic
solids. Spin distributions and net magnetic moments are calculated for nanoparticles of …

Magnetic solids should, under certain circumstances, show macroscopic quantum behavior,
in which coherence exists between completely distinct magnetization states, each involving …

Spin systems can undergo quantum tunneling with classically degenerate minima. In some
cases, the amplitudes from symmetry-related trajectories can interfere destructively …

Magnetic relaxation experiments constitute a unique method of determining the nature of
fluctuations in dissipative magnetic systems. At high temperatures these fluctuations are …

Magnetism of nanoparticles is an area of intense development that touches many fields
