Abstract: The present embodiments relate to a PMR write head with a trailing shield that comprises a FeCoNiM composition. The FeCoNiM composition can be formed via an electroplating process by adding Fe2+, Co2+, Ni2+ and a transition metal salt to an aqueous solution comprised of other additives in an electroplating cell that has an Ni or Co as the anode. The plated HD magnetic material as the trailing shield in a PMR writer can minimize a wide area track erasure (WATE). Further, a high moment high damping shield can lower bit error rate (BER) and increase aerial density capability (ADC) of the write head.

Abstract: The present application relates to a method for statistical distribution characterization of dendritic structures in original position of single crystal superalloy, and relates to the technical field of analysis of metal material composition and microstructure, comprising the following steps: step 1, processing a to-be-tested sample and determining a calibration coefficient; step 2, obtaining a two-dimensional element content distribution map of the to-be-tested sample; and step 3, determining the number and average spacing of primary dendrites. A composition distribution region analyzed in the present application is larger than the area of a distribution region of the traditional microscopic analysis method, and the sample preparation is simple. The distribution, number and average spacing of the primary dendrites can be obtained without metallographic corrosion sampling.
