New type of active device based on galvanomagnetic effect

Autor: K. Kakuno

Publikováno v: Journal of Applied Physics. 81:8105-8108

A new type of active device composed of metals is fabricated based on the galvanomagnetic electromotive force effect, which is at the origin of the magnetoresistance effect and of the so-called planar Hall effect. A power gain (the ratio of the signa

Propagation of Magnetoelastic Waves in Cold-Drawn Amorphous Wires

Autor: K. Kakuno, S. Masuda, Y. Takemura

Publikováno v: Journal of the Magnetics Society of Japan. 19:477-480

The attenuation constants of magnetoelastic waves in cold-drawn amorphous Fe-Si-B wires were precisely measured by an improved method using the partial annealing technique. Experimental results show that the attenuation constant decreases with the fr

Magnetoresistance Effect in Ni-Fe Thin Films Measured by Use of a High Magnetic Field

Autor: Y. Takemura, S. Miura, K. Kakuno, Tsutomu Yamada, A. Tsukimori

Publikováno v: Journal of the Magnetics Society of Japan. 19:273-276

The anisotropic magnetoresistance (MR) effect, galvano- magnetic electromotive force effect, and forced MR effect in Ni-Fe thin films were studied by using high magnetic fields up to 15 T. These effects were measured in Ni-Fe thin films with various

High power test of the first C-band (5712 MHz) 50 MW PPM klystron

Autor: K. Ohhashi, T. Shintake, Hiroshi Matsumoto, H. Taoka, Y. Ohkubo, K. Kakuno

Publikováno v: PACS2001. Proceedings of the 2001 Particle Accelerator Conference (Cat. No.01CH37268).

Hot isostatic pressing (HIP) technique has been applied to fabricate a magnetic circuit in a PPM klystron. Simply stacking disks of the magnetic stainless-steel (Mag-SUS) and oxygen-free-copper (OFC) alternatively, and processing in a HIP vessel fill
