    • In a spin valve type magnetoresistance effect film, an antiferromagnetization promote layer is formed on a surface of an antiferromagnetic layer remote from a surface thereof abutting a ferromagnetic layer. The antiferromagnetic layer is made of a compound containing Mn and having a CuAu—I type regular crystal structure. The antiferromagnetic layer has a characteristic requiring a heat treatment for generating the exchange coupling relative to the ferromagnetic layer. The antiferromagnetic layer after the heat treatment is oriented on the (111) crystal orientation surface. The ratio Lp/La of a lattice constant Lp in the closest packed surface of the antiferromagnetization promote layer relative to a lattice constant La in the (111) crystal orientation surface of the antiferromagnetic layer is in the range of 0.9 to 1.1. Accordingly, the regulating temperature of the antiferromagnetic layer can be lowered so that the exchange coupling to the ferromagnetic layer can be generated at a heat treatment temperature as low as possible (for example, no higher than 250° C.). The thus obtained spin valve film is subjected to only quite small deterioration of spin valve film characteristics (for example, MR ratio).
    • 在自旋阀型磁阻效应膜中,在与铁磁层相邻的反铁磁层的表面上形成反铁磁化促进层。 反铁磁层由含Mn的化合物制成,具有CuAu-I型规则晶体结构。 反铁磁层具有需要热处理以产生相对于铁磁层的交换耦合的特性。 热处理后的反铁磁层取向于(111)晶体取向表面。 反铁磁性促进层的最接近的填充表面的晶格常数Lp的比Lp / La相对于反铁磁性层的(111)结晶取向面的晶格常数La的变化范围为0.9〜1.1。 因此,可以降低反铁磁层的调节温度,使得可以在尽可能低的热处理温度(例如不高于250℃)下产生与铁磁层的交换耦合。 如此获得的自旋阀膜仅经受非常小的自旋阀膜特性劣化(例如,MR比)。
