Abstract: This paper reports on the results of the investigation into the magnetocaloric properties of sandwich structures of La$_{1-x}$K$_{x}$MnO$_{3}$ manganites with $x$ = 0.11 (LKM11), 0.13 (LKM13), and 0.15 (LKM15) in magnetic fields of up to 18 kOe. The results of the analysis of the field and temperature dependences of the magnetocaloric effect in the structures LKM11 + LKM13 and LKM13 + LKM15 have demonstrated that the use of sandwich structures increases the efficiency of magnetic cooling in a magnetic field of 18 kOe by 45%.
