Magnetic properties of small iron clusters in a molecular beam are investigated by examining their deflections in a Stern-Gerlach magnet. The magnetization is probed as function of magnetic field, temperature and cluster size. The clusters are either heated with light from a pulsed laser which affects the vibrational temperature, or cooled in supersonic expansions which primarily affect the rotational temperature. We find that at temperatures up to 1500 K the magnetic moments of laser heated Fe 120–140 clusters are much larger than predicted either in the Heisenberg model or compared with the bulk values suggesting a stronger exchange interaction. Furthermore, rotationally cold clusters show anomalously magnetization which is non-linear with the applied field. This effect is found to be related to the anisotropy coupling of the total spin with the cluster framework. A model taking this effect into account and assuming a resonant coupling between the rotations and the Larmor precession of the spins gives good qualitative agreement with the observations.

A qualitative proof of diamagnetic non-zero magnetization based on the electromagnetic induction law is presented in this paper. Modeling diamagnetic phenomena as a result of Larmor precession or effect of the electromagnetic induction’s law in scale of one hydrogen-like atom performed in classical physics contributes to formation of obviously incorrect idea of the diamagnetic magnetization process in students. It is well-known that the average magnetic moment of a diamagnetic calculated with the help of classical statistics laws is zero which can be explained by quantum character of magnetic phenomena. On the contrary, electromagnetic induction’s law is effective both in classical and quantum physics. Applying it to the diamagnetism problem will allow to solve it for the diamagnetic in whole and to avoid averaging which is proved in the present paper.

Larmor precession of the first 2+ states of 182W and 184W has been observed in an iron alloy containing 5 atom % W. The levels were Coulomb excited with 2.5 MeV protons. The hyperfine energy in 182W is the same as that found by Mössbauer absorption. The variation of the field up to 300 °K is less than 6%. A comparison of g factors measured by the hyperfine field and the external field suggests the existence of a hyperfine anomaly.
