Abstract

Experimentally obtained linewidth in F.M.R. of Zn2Y is analyzed numerically on the basis of two‐magnon, three‐magnon and four‐magnon relaxation processes. In the analyzing procedure of three‐magnon linewidth, the effective exchange constants are determined to to be D⊥=0.15×10−9 Oe cm2 and D″=9.3×10−9 Oe cm2 within and between the crystallographic c planes. The two‐magnon linewidth induced by surface imperfection is discussed in consideration of scattering due to multipole demagnetizations of the imperfections. The four‐magnon linewidth is observed for the first time and analyzed successfully.
