摘要：

The effect of NiFe texture on the exchange coupling field and coercivity of Ta/NiFe/FeMn films was studied by varying the deposition conditions of de magnetron-sputtered NiFe films. By decreasing argon pressure or by increasing substrate bias, strongly textured, large grains of NiFe(111) were grown, yielding highly oriented FeMn(111) texture. Well oriented NiFe(111)/FeMn(111) films yielded the highest exchange anisotropy (0.14 erg/cm(2)), lowest coercivity (approximate to 2 Oe), and highest blocking temperature (200 degrees C) ever reported.
