摘要
We report the distribution profiles of blocking temperature (T-b) in RuxRuyMn-NiFe interfaces with comparison of FeMn, NiMn, and PtMn. The distribution of T-b at the temperature around 120 similar to 150 degrees C decreased with increasing Rh content. The FWHM of the distribution profile in Ru4Rh14Mn is one half of that in ordered phase NiMn and PtMn. The unblocked ratio at 125 degrees C decreases with increasing Rh content, and becomes a minimum in Ru4Rh14Mn, which is one half of FeMn.
