Origin of four-fold anisotropy in square lattices of circular ferromagnetic dots

Autor: Kakazei, G. N., Pogorelov, Yu. G., Costa, M. D., Mewes, T., Wigen, P. E., Hammel, P. C., Golub, V. O., Okuno, T., Novosad, V.

We discuss the four-fold anisotropy of in-plane ferromagnetic resonance (FMR) field $H_r$, found in a square lattice of circular Permalloy dots when the interdot distance $a$ gets comparable to the dot diameter $d$. The minimum $H_r$, along the latti

Perturbation of magnetostatic modes observed by FMRFM

Autor: Urban, R., Putilin, A., Wigen, P. E., Liou, S. -H., Cross, M. C., Hammel, P. C., Roukes, M. L.

Magnetostatic modes of Yttrium Iron Garnet (YIG) films are investigated by ferromagnetic resonance force microscopy (FMRFM). A thin film ``probe'' magnet at the tip of a compliant cantilever introduces a local inhomogeneity in the internal field of t

Spin-reorientation in YbFeO_3

Autor: Bazaliy, Ya. B., Tsymbal, L. T., Kakazei, G. N., Kamenev, V. I., Wigen, P. E.

Publikováno v: Phys. Rev. B, 72, 174403 (2005)

Precise measurements of YbFeO_3 magnetization in the spin-reoirentation temperature interval are performed. It is shown that ytterbium orthoferrite is well described by a recently developed modified mean field theory developed for ErFeO_3. This valid
