K dopant effect on La0.7KxCa0.3-xMnO3 (x=0, 0.05, 0.1) perovskite compounds: the structural, magnetic and magnetocaloric properties
La 0.7 K x Ca 0.3 - x MnO 3 ( x = 0 , 0.05, 0.1) perovskites were prepared by sol–gel method. The K-doped effect was determined by the structural, magnetic, and magnetocaloric properties of the compounds. In the crystal structure of K-doped La 0.7 Ca 0.3 MnO 3 , Mn–O–Mn bond angle slightly increases...
