III Investigations of ferromagnetic alloy films by XMCD1. By using XMCD and SQUID magnetometry, the spin and orbital moments of Fe and Co in the Co_(0.9)Fe_(0.1)(50nm) are studied. Compared with single-element film, the spin moment of Co remains constant while that of Fe reduced from 1.98 to 1.63μB. The contributions of different elements in the film is, m_ : m_ - 10.5 : 89.5. The average magnetic moment (1.90μB) determined by XMCD is in agreement with that (1.82μB) obtained from SQUID measurements. Utilizing XMCD spectra in-plane element-dependent magnetic anisotropy in Co_(0.9)Fe_(0.1) films has been investigated. Apart from known field-induced easy axis during film growth, a soft axis perpendicular to it was observed, and hard axes are 66° away from the easy axis.

The above multiple changes will produce 2 kinds of waves, Matter waves and mechanical waves that spread at the same time. Because the electromagnetic wave is a matter wave, it is the medium. Since the multiple exchanges of the electrons state can be regarded as electrical vibration, and the vibrated electrons have magnetic fields and electrical fields at the same time, the electromagnetic wave will be produced. Then, because the electron itself is a matter micro particle, it can produce mechanical waves which can propagate outside with electrical magnetic waves.

这种状态改变的多次往复，就会产生两种波，一种物质波，即电磁波；一种机械波，并且这种机械波是以同次产生的电磁波为媒质进行传播的，，这是因为本种状态的多次往复，可以看作是一种电子振动，振动的电子同时具有磁场和电场，所以能够产生电磁波，又因为电子本身是一个物质微粒所以他能够产生机械波，并且是横波，并随电磁波进行向外传播。
