Magnetic Properties of Nd12Co6Pb Compound何维,张吉亮,曾令民摘 要:<正>The magnetic and magnetocaloric properties for the Nd12Co6Pb compound were investigated. The Curie temperature Tc of the magnetic transition of Nd12Co6Pb compound is 194 K. The experimentally determined magnetic effective paramagnetic moment isμeff= 12.36μB per formula unit (3.49μb per Nd......
; (2) where M is the net overall magnetic moment; a is the lattice parameter. The cation distribution of the NZTF ferrite thin films is (Zn0.5Fe0.5)[Ni0.5+xTixFe1.5-2x]O4. Due to antiferromagnetic coupling, the net overall magnetic moment is equal to the result of magnetic moment from B sites minus magnetic moment from A sites, M=MB-MA......
