Improving Sensitivity and Resolution of Planar Magnetic Inductive Sensors by Optimizing Gap Between Magnetic Films

Cr thin films are often used as underlayers for Co alloy magnetic thin films, such as Co1, CoNi2, and CoNiCr3, for high density longitudinal magnetic recording. It is belived that the role of the Cr underlayer is to control the growth and texture of the Co alloy magnetic thin films, and, then, to increase the in plane coercivity of the films. Although many epitaxial relationship between the Cr underlayer and the magnetic films, such as ﹛1010﹜Co/ {110﹜Cr4, ﹛2110﹜Co/ ﹛001﹜Cr5, ﹛0002﹜Co/﹛110﹜Cr6, have been suggested and appear to be related to the Cr thickness, the texture of the Cr underlayer itself is still not understood very well. In this study, the texture of a 2000 Å thick Cr underlayer on Nip/Al substrate for thin films of (Co75Ni25)1-xTix dc-sputtered with - 200 V substrate bias is investigated by electron microscopy.

The article is devoted to the development of a secondary converter for measuring the speed of turbo-pump aggregates of rocket engines. The principle of the induction speed sensor is considered in the article. A method is proposed for generating output pulses from signals of induction speed sensors, which consists in the preliminary integration of the signals of the speed sensor. This method allows to increase the reliability and accuracy of the formation of signals of induction speed sensors, as well as to increase the noise immunity of the secondary converter and significantly increase the dynamic range of measuring the speed. The data of flight tests of the developed secondary converter are given.
