抄録
Shifts of ESR lines in impure two-dimensional magnets K2MncMg1−cF4 were investigated in X-band region at room temperature. The theory, which includes the terms arising from the two-dimensionality of spin distribution in the Kubo-Tomita theory, predicts the angular variation of sin2 θ(1+9 sin2 θ) cos 2φ or sin2 θ(3 cos2 θ−1) cos 2φ for the shifts according as all q modes or only q=0 mode in the dipolar interaction are concerned. Here, θ and φ are the polar and azimuthal angles, respectively, of the c axis with respect to a coordinate system in which an external field is along the polar axis. The shifts observed in K2Mn0.43Mg0.57F4 were explained by taking account of the dominancy of the q=0 mode and the effect of the long time tails in the spin correlation function in the impure system.
