Abstract : An experimental study was made of physical, chemical, and magnetic properties of thin nickeliron films prepared by electrochemical deposition. A magnetic anneal of nickel-iron films is described. Magnetic film properties necessary for memory applications and their measurement are discussed. Films with a wide range of thicknesses and compositions were prepared to determine optimum electrochemical deposition conditions. Arrays of films were evaluated to determine the effects of various combinations of thickness and bit diameter on coercivity, anisotropy, and loop squareness properties. (Author)
