An Experimental Study of Head Instabilities in TMR Sensors for Magnetic Recording Heads with Adaptive Flying Height
We did an experimental study to investigate the effect of the thermal stress due to the heater for adjusting adaptive flying height (AFH) on the readability and instability of tunneling magnetoresistance (TMR) sensors. The slider head consists of a small heater nearby the read/write elements for controlling the clearance between the read/write elements and the recording medium of the magnetic r...
متن کاملThe theory of GMR and TMR in segmented magnetic nanowires
We calculate the resistivity and Giant Magnetoresistance (GMR) of a segmented nanowire consisting of two ferromagnetic segments separated by a thin paramagnetic spacer. The quantization of the electron motion due to the small nanowire cross-section is taken into account; s − d electron scattering gives rise to different mean free paths for spin-up and spin-down s-electrons. The calculated resis...
متن کاملMetal-insulator type nano-granular magnetic thin films -soft magnetic properties, TMR effect and their applications-
Metal-Insulator type nano-granular magnetic (NGM) thin films have been noteworthily developed as several functional magnetic materials. The formation of nanogranular structure is strongly related to the magnitude of heat formation (H) of intergranule materials. Forming a larger H allows a clearer granular structure to be obtained. Soft magnetic properties and TMR effect of NGM films are revie...
متن کاملANALYSIS OF SOME MAGNETIC PROPERTIES OF DILUTED MAGNETIC SEMICONDUCTORS
The susceptibility and specific heat experimental results of the diluted magnetic semiconductors (DMS) are incorporated in a model based on short-range as well as long-range interaction in a random may of magnetic ions. The so-called nearestneighbor pair approximation (NNPA) is applied. It appears that the calculated values of zero field specific heat and Curie-Weiss temperature based on th...
متن کاملMechanistic Features of Nanodiamonds in the Lapping of Magnetic Heads
Nanodiamonds, which are the main components of slurry in the precision lapping process of magnetic heads, play an important role in surface quality. This paper studies the mechanistic features of nanodiamond embedment into a Sn plate in the lapping process. This is the first study to develop mathematical models for nanodiamond embedment. Such models can predict the optimum parameters for partic...
