Abstract: The effect of the thermally induced magnetoelastic effect on the switching field of quasi- homogeneous magnetization of planar Ni particles of micron size with configurational anisotropy is investigated. Square Ni particles of two types are formed on the surface of monocrystalline lithium triborate. It has been experimentally shown that when the temperature of the structure changes by $\pm$ 20$^\circ$C relative to the particle formation temperature (50$^\circ$C), both a decrease and an increase in the particle switching field are observed. This is due to the magnetoelastic anisotropy induced in them when the temperature changes due to the difference in the coefficients of thermal expansion of the substrate along different crystal axes.

Keywords: thermally induced magnetoelastic effect, submicron particles, switching field, magnetic force microscopy, quasi-uniform magnetization, configuration anisotropy.
