摘要： In this paper, we focus our attention on the performance of read heads under the off-track reading condition when the reader is under the influence of the recorded magnetization patterns on the medium, and analyze how the magnetic field due to various data patterns impacts the read head behavior. The analysis is based on the micromagnetic modeling of the state of magnetization in read sensor considering its external magnetic fields due to both the hard bias and the media magnetization pattern. The effects of various magnetization patterns on media are analyzed. The effect of thermal magnetic agitation of the gyromagnetical precession of magnetizations is also evaluated. It is shown that to account for such effect is important for evaluation of magnetic recording schemes for extremely high density.

Layered Topological Insulators and Semimetals for?Magnetoresistance Type Sensors
摘要： Magnetoresistance (MR) type sensors are transducers that can vary their resistances sensitively in response to an applied magnetic field. Recently, topological quantum materials have drawn the increased attention for sensor applications due to their novel MR effects. Here, a range of MR effects occurring in the layered 3D topological insulators and topological semimetals are briefly reviewed. The MR effects include the extremely large nonsaturating MR, the giant anisotropic MR, and the unique spin-valve-like MR. The large MR ratios, the high MR anisotropy, and the low 1/f noise allow sensors to have the high sensitivity over a wide range of temperatures and magnetic fields. It is anticipated that the layered topological quantum materials with their excellent MR performance and structural flexibility would provide an ideal platform for new-generation magnetic sensor applications.
