Abstract

STRUKTUR DAN SIFAT MAGNETIK La1-xCaxMnO3 DENGAN x = 0,27 DAN 0,47. Struktural dan sifat magnetik La1-xCaxMnO3 dengan x = 0,27 dan 0,47 telah dikaji menggunakan difraksi serbuk neutron dan pengukuran magnetisasi. Pada suhu kamar dan suhu rendah, semua sampel memiliki struktur ortorombik dengan grup ruang Pnma. Sampel x = 0,47 menunjukkan campuran antiferromagnetik dan feromagnetik dengan momen magnetik 1,30 μB dan suhu Curie adalah 260 K, sedangkan sampel x = 0,27 menunjukkan feromagnetik dengan momen magnetik 3,10 μB dan suhu Curie adalah 197 K.

ABSTRACT

THE STRUCTURALAND MAGNETIC PROPERTIES OF La1-xCaxMnO3 WITH x = 0.27 AND 0.47. We have studied the structural and magnetic properties for La1-xCaxMnO3 with x = 0.27 and 0.47 using neutron powder diffraction and magnetization measurements. At room and low temperature, all samples have the orthorhombic structure with space group Pnma. The sample x = 0.47 shows the antiferromagnetic mix a ferromagnetic with the magnetic moment and the Curie temperature are 1.30 μB and 260 K, respectively while the sample x = 0.27 is a ferromagnetic with the magnetic momentand the Curie temperature are 3.10 μB and 197 K, respectively.
