This article discusses the influence of the geometry of mesoscopic structures based on Ni₃Pt nanoparticles on the magnetothermal characteristics to maximize the magnetocaloric response. Nanostructured samples in the form of arrays of nanocylinders and nanowires were made using a combination of electron-beam lithography and electrochemical deposition methods. It was determined that the change from nanoparticles to nanostructured objects contributes to an increase in the magnetocaloric effect and change of the operating temperature range.
