The new way to optimize the magnetothermal characteristics of nanosystems

0minút, 33sekúnd

A technological procedure for producing arrays of nanomagnets based on Ni3Pt nanoparticles has been developed. The arrays of nanomagnets were produced by e-beam lithography and electrochemical deposition. This approach allows the formation of the structures with precisely defined geometrical parameters. It has been established experimentally that by a change of a period of nanomagnet array it is possible to change the magnetocaloric response and adjust the optimum operating temperature range of the system. The results of this study were published in the Journal of Magnetism and Magnetic Materials with impact factor of 3.046 [S. Vorobiov, D. Tomasova, V. Girman, H. You, E. Čižmár, M.
