If someone knows experimental detail of this paper (doi:10.1115/1.3424301)by Kenzo Miya. I want to know total and free length of the cantilever in the experiments. It is not mentioned in one other sister paper( doi: 10.1115/1.3153672) where critical magnetic fields are tabulated. This paper is written by K. Miya, T. Takagi, Y. Ando.
