There is a new magnetic alloy called Finemet which has very constant μ′pQf up to ∼2 kG and is very stable at high magnet flux density and temperature. It may be a good candidate for high-gradient rf cavities.However, it has a rather low quality factor and is therefore very lossy. We compare the pros and cons of Finemet versus the common ferrite, when used in low-energy accelerating cavities, in...

The development of Fe73.5Si13.5B9Nb3Cu1 ~FINEMET! by Yoshizawa et al. and Fe88Zr7B4Cu1 ~NANOPERM! by Inoue et al. have shown that nanocrystalline microstructures can play an important role in the production of materials with outstanding soft magnetic properties. The FINEMET and NANOPERM materials rely on nanocrystalline a-Fe3Si and a-Fe, respectively, for their soft magnetic properties. The mag...

The magnetic and structural properties of an Si-rich grade FINEMET alloy with a composition of Fe73.5Si16.1B6.4Nb2.9Cu1.1 in at% [Fe82.7Si9.1B1.4Nb5.4Cu1.4 (wt%)] were investigated after primary and secondary crystallization of ribbon samples. Optimally annealed ribbons exhibited a homogeneous microstructure composed of B7 nm DO3 nanocrystals surrounded by the retained amorphous phase. This is ...

A two staged 62 TeV center of mass hadron collider is proposed. In the first stage the center of mass energy will be 14 TeV with 2 Tesla dipole magnets. With Superbunch beams, the luminosity is expected to be increased by a factor of 15, compared with conventional acceleration using RF cavities. To accelerate Superbunch beams, the barrier bucket induction cells and acceleration induction cells ...

5-fluoro-2’-deoxycytidine (FdCyd), a DNA methyltransferase inhibitor, has been shown to allow reexpression of tumor suppressor genes. However, in vivo, FdCyd experiences rapid metabolic conversion by cytidine deaminase (CD) to active cytotoxic metabolites 5-fluoro-2’-deoxyuridine (FdUrd), 5-fluorouracil (FU), and inactive 5-fluorouridine (FUrd). Preclinical studies coadministering FdCyd with a ...

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 ...

Thermomagnetic processing of films the Finemet type with an easy magnetization axis in plane under action a constant and rotating magnetic field was carried out order to obtain isotropic state. After heat treatment field, reoriented along line as result which domain walls were oriented new axis. thermomagnetic regions different anisotropy patterns, including regions, revealed.
