Magnetic Alloy, Finemet®, is a material developed in Japan. We have been developing Magnetic Alloy-loaded cavities for approximately 30 years. Although the developments aimed to develop RF system to accelerate very high intensity proton beam, fruitful spin-outs were born through the researches. We will summarize the history of the cavity developments, successful status of beam acceleration of J-PARC synchrotrons, and future prospect of the cavities.
