摘要

近年来，用

Fe的内转换电子穆斯堡尔谱学（CEMS）对离子注入层的磁性进行了一些研究

[1-5]

。这些试样的泡径较大。随着磁泡技术向小泡径发展，而小泡径材料的垂直膜面的磁单轴各向异性较大，因此，它将给离子注入带来什么新的问题就为人们所关心。本文报道我们用CEMS对小泡径磁泡石榴石材料离子注入层所作的一些研究。

Abstract

This paper describes an

Fe conversion electron Mössbauer spectrcscopic study of small bubble diameter material. The nominal composition of the film is (YLuBi)

-(FeGa)

. After a dosage of 5×10

to 1×10

-2

100 keV Ne

implantation

peaks of 2 and 5 of CEMS are emerged

indicating that the magnetization vector M

of the surface layer of the film is toward the film plane. It was found that the stress induced magnetic plannar anisotropy owing to the dosage of ion implantation is not necessary to be very large. While d=2×10

-2

only paramagnetic spectra are obtained but the and d site spectrum is distinguishable. When d≥7×10

-2

hard bubbles are suppressed. High temperature 1050℃ annealling is required to restore the hyperfine field to the value in the as-grown state

however

peaks 2 and 5 are present in the spectra and hard bubbles are still suppressed.
