Notes:
The optical, electrical, and magnetic properties of magnetic Nd15Fe77B8 and nonmagnetic Nd5Fe62B33 films have been investigated. It has been found that within the visible (wavelengths 4400–6400 A(ring)) the films are transparent with thickness less than 800 A(ring) for magnetic films and 1500 A(ring) for nonmagnetic films. This is due to the difference of the magnetic permeability μ between films. The oscillatory behavior with thickness of the films is observed in the film samples. The anomalous behaviors near the Curie temperature for both bulk- and film-type samples are similar to that of the type-III ferromagnets. The temperature at which the electrical resistance of the film-type samples increases abruptly varies from 620 K for 1000 A(ring) to 650 K for 2000 A(ring).
