Influence of thermoinduced magnetoelastic effect on domain structure of planar Ni microparticles

Results of studying the domain structure planar Ni microparticles formed on single-crystal substrates from lithium niobate and potassium titanyl phosphate at different temperatures are presented. The dependence sizes sample temperature was studied. It is shown observed change caused by magnetoelastic effect, which arises due to difference in thermal expansion coefficients substrate as changes. shown, magnetic domains, up creation a state with quasi-homogeneous magnetization may be set during formation. Keywords: force microscopy, remagnetization, niobate, phosphate, temperature.
