Minor Loop Scaling Rules for Finemet Type Soft Magnetic Cores

Investigation on the crystallization mechanism difference between FINEMET® and NANOMET® type Fe-based soft magnetic amorphous alloys

Investigation of Scaling Properties of Hysteresis in Finemet Thin Films

We study the behavior of hysteresis loops in Finemet Fe73.5Cu1Nb3Si18.5B4 thin films by using a fluxometric setup based on a couple of well compensated pickup coils. The presence of scaling laws of the hysteresis area is investigated as a function of the amplitude and frequency of the applied field, considering sample thickness from about 20 nm to 5 μm. We do not observed any scaling predicted ...

Lascu MAGNETIC SUSCEPTIBILITY LOGGING FOR CORES

The magnetic susceptibility of a natural or synthetic material is a measure of its ‘magnetizability’ in the presence of a small magnetic field. Once the applied field is removed, the magnetization induced in the analyzed material reverts to the initial magnetized state of the substance. In mathematical terms, volume magnetic susceptibility (κ) is defined as the ratio between induced magnetizati...

An Electrical Circuit Model for Magnetic Cores

In Figure 2, the shape is the same as Fig. I, but the axis labels and values have been changed. Figure 2 shows the characteristic of a specific core made from the material of Figure I. The flux density axis Magnetic Fundamentals: Units commonly used in magnetics design are given in Table I, along with conversion factors from the older CGS system to the SI system (sysfeme infernationalrationaliz...

Scaling Turbo Boost to a 1000 cores

The Intel® CoreTM i7 processor code named Nehalem provides a feature named Turbo Boost which opportunistically varies the frequencies of the processor’s cores. The frequency of a core is determined by core temperature, the number of active cores, the estimated power consumption, the estimated current consumption, and operating system frequency scaling requests. For a chip multi-processor(CMP) t...
