Hysteresis loops and magnetostriction were measured on ring-shaped Fe85Ga15 samples. The samples were annealed at T = 980 °C for 100 h and cooled from annealing temperature in two different ways: one was slowly cooled in an oven and the other one was quenched in cold water. X-ray diffraction results showed a strong texture in these samples, which is dependent on the co... View full abstract»

• ### A Study of Multitrack Joint 2-D Signal Detection Performance and Implementation Cost for Shingled Magnetic Recording

Publication Year: 2014, Article Sequence Number: 3100906
Cited by:  Papers (2)
| | PDF (1222 KB) | HTML

Shingled magnetic recording is a promising option to sustain the historical areal density growth of hard disk drives while retaining conventional heads and media. Nevertheless, highly scaled shingled magnetic recording is subject to severe intertrack interference (ITI), fewer grains per channel bit and therefore lower signal-to-noise ratio (SNR). This naturally demands 2-D read channel signal proc... View full abstract»

| | PDF (651 KB) | HTML

Dielectric resonances in the 37-42 GHz frequency band in the single crystal barium hexaferrite that occur well below the ferromagnetic resonance (FMR) have been investigated. Sample dimensions have been chosen so that the mode frequency is lower than the spin-wave excitation (in this case, the natural domain resonance) frequency. Such dielectric mode frequencies, being a function of both permittiv... View full abstract»

A recently proposed technique to control the satellite attitude using a magnetically levitated sphere requires the development of suitable models of its dynamics. One of the phenomena that can affect motion of the system are eddy currents induced in the stator of the actuator due to time variable magnetic field generated by rotational motion of a permanent magnet rotor. We present an analytical mo... View full abstract»

Magnetic stimulation is gaining importance as an alternative to electrical stimulation in neurorehabilitation because it offers deep penetration and low pain. However, presently available equipment is not ideal for this purpose and sometimes even unsuitable. Furthermore, it is not known what physical conditions a coil has to provide for efficient stimulation. To solve these two problems, we set up... View full abstract»

High-order surface impedance boundary conditions are introduced in a 2-D variational formulation in terms of magnetic vector potential. The formulation is then discretized using the isogeometric analysis method, based on nonuniform rational B-splines, allowing an efficient computation of the curvature of the conductor surface. The formulation is validated through some test cases, already solved vi... View full abstract»

Improvised asymptotic boundary conditions are a sparse but approximate method of solving open boundary problems. Since this method approximates unbounded space as series of isotropic shells, it can be readily implemented in virtually any finite element solver without the need for additional code. A previous paper addressed application of this technique to magnetic problems described with a vector ... View full abstract»

The design of control strategies for permanent magnet synchronous machines (PSM) is almost exclusively based on classical dq0-models. These models are, however, not able to systematically describe saturation or nonhomogenous air gap geometries typically occurring in PSM. This paper deals with a framework for the mathematical modeling of PSM based on magnetic equivalent circuits. Different to exist... View full abstract»
