• ### Effect of Variable Biquadratic Exchange Coupling on the Magnetic Hysteresis of Uniaxial Antiferromagnetic Co/Ru/Co Films

Publication Year: 2007, Page(s):4056 - 4059

| | PDF (157 KB) | HTML

We investigated biquadratic exchange coupling strength in sputtered uniaxial antiferromagnetic Co/Ru/Co trilayers, which can be tuned by applying a magnetic field perpendicular to the sample surface during deposition. The perpendicular field induces a columnar grain structure that results in a perpendicular magnetic anisotropy for single Co layers. The perpendicular magnetic anisotropy is detected...

• ### Soft Magnetic Properties of Obliquely Deposited Co–Zr–O Films

We have studied obliquely sputtered Co-Zr-O films. We found that oblique deposition gives rise to the formation of columnar morphology and thus higher perpendicular magnetic anisotropy in the films, which finally results in the occurrence of stripe domains and degradation of soft magnetic properties. Applying substrate bias during Co-Zr-O film deposition gave some improvement in magnetic softness ... View full abstract»

We propose a novel method for extracting the electromagnetic parameters (complex permittivity and permeability) of magnetic thin-film materials. The method extracts electromagnetic parameters of the magnetic thin films from effective electromagnetic parameters by using the supported vector machine (SVM). We validated the method in the frequency range of 1-8 GHz. The results show that the errors fo... View full abstract»

| | PDF (1527 KB) | HTML

In this part of the paper, we focus on implementation of a hierarchical multiscale approach for modeling high-frequency electromagnetic processes in power transformers. We present a large-scale 3D computer model for calculating magnetic fields in a transformer and evaluating effective parameters (inductance and resistance) of its windings and losses. The model accounts for complex, anisotropic, an... View full abstract»

An eccentric rotor creates an electromagnetic force between the rotor and stator of an electrical machine. This force tends to further increase the rotor eccentricity and may severely degrade the performance of the machine, causing acoustic noise, vibration, excessive wear of bearing, rotor and stator rubbing, and so forth. Parallel connections are known to be a simple yet effective remedy for the... View full abstract»

The paper describes a neural network method for optimal design of a switched reluctance motor (SRM). The approach maximizes average torque while minimizing torque ripple, considering mainly the stator and rotor geometry parameters. Before optimization takes place, an experimental validation of the SRM model, based on the finite-element method, is performed. The validation predicts average torque a... View full abstract»

For medical diagnoses and treatments, it is often desirable to wirelessly trace an object that moves inside the human body. A magnetic tracing technique suggested for such applications uses a small magnet as the excitation source, which does not require the power supply and connection wire. It provides good tracing accuracy and can be easily implemented. As the magnet moves, it establishes around ... View full abstract»

As the density in optical data storage systems increases, a drive capable of tilt control thus becomes necessary in order to improve the tilt margin as the coma aberration is accordingly increased. In this paper, we propose an innovative three-axial actuator based on a traditional four-wire scheme with an additional pair of tilting magnets. The proposed coil-driven servo can independently compensa... View full abstract»

We report on fabrication of discrete tracks on perpendicular magnetic recording (PMR) media with an e-beam lithographical process. We studied the recording performance of the e-beam media on a spinstand in parallel with conventional PMR media. Discrete track media show significant reduction in adjacent track erasure (ATE). We studied and quantitatively measured the source of the ATE improvement, a... View full abstract»

• ### Use of Low-Density Parity-Check Codes for Dominant Error Events Detection and $k$-Constraint Enforcement

Publication Year: 2007, Page(s):4113 - 4116
| | PDF (364 KB) | HTML

In this paper, we propose to leverage the simple and explicit parity checks inherent in low-density parity-check (LDPC) codes to detect dominant error events without code rate penalty. This is enabled by enforcing a very weak constraint on the LDPC code parity check matrix structure. Such a constraint can be readily satisfied by most structured LDPC codes reported in the open literature, such as q... View full abstract»

We report a silicon area efficient method for designing a quasi-cyclic (QC) low-density parity-check (LDPC) code decoder. Our design method is geared to magnetic recording that demands high code rate and very high decoding throughput under stringent silicon cost constraints. The key to designing the decoder is to transform the conventional formulation of the min-sum decoding algorithm in such a wa... View full abstract»
