Magnetic nanoparticles are applicable in imaging, diagnosis, therapy, and biomaterial separation. The magnetic nanoparticles comprise a core represented as Fe<SUB>x</SUB>M<SUP>a</SUP><SUB>v</SUB>Z<SUB>y </SUB>and a shell of an inner-transition element M<SUP>b </SUP>or the compound thereof, wherein M<SUP>a </SUP>is an inner-transition element, Z is an element of the group Vla, x is greater or equal to 0, and v, y are positive numbers. The surface of the shell is optionally modified by liposome, polymer, aliphatic compound, aromatic compound or combinations thereof.
