“…Magnetic entropy change on divalent alkaline-earth-doped lanthanide manganites with various compositions have been reported widely [3,4,12,[16][17][18][19][20][21][22][23][24][25][26][27][28]. However, investigations on monovalent alkali-metal-doped manganites are relatively few [7,29,30]. In the present communication, we report our recent results on the magnetocaloric effect in good quality La 1−x K x MnO 3 (x = 0.05, 0.10, 0.15), prepared by pyrophoric technique and having their T C ranging between 260 and 309 K. It is found that these materials display significant magnetic entropy changes induced by low magnetic field changes.…”
