¡¡¡¡Zhang Zhi-dong, born in June 1963.
He received B.S. degree in the department of Physics, Nanjing University,
in 1983. He became a graduate student of the Institute of Metal
Research (IMR), Chinese Academy of Sciences (CAS), under supervisor
of Academician Prof. Y.C. Chuang and Prof. C.H. Wu and received
his M.S. degree in 1986. He received his Ph.D degree in 1989, promoted
by co-supervisors of Academician Prof. Y.C. Chuang, Prof. X.K. Sun
and Prof. F.R. de Boer.
¡¡¡¡During his Ph.D study, Zhang Zhi-dong
focused his interest in structural and magnetic properties of ternary
Fe-based rare-earth transition-metal intermetallics. He systematically
investigated the structure and magnetic properties of Nd-Fe-B and
Nd-Fe-C type compounds. Based on the single ion theory, a model
was established to interpret non-linear composition dependence of
magnetocrystalline anisotropy coefficients. Based on the results
in his thesis, more than 10 papers were published in international
journals, like Phys.Rev.B.
¡¡¡¡Dr. Zhang Zhi-dong has been engaged
in research on the fields of magnetism, magnetic materials and their
applications. His work has involved the spin wave theory, new rare-earth
transition-metal compounds, nanocomposite magnetic materials, magnetic
phase transitions and applications of magnetic materials. He became
an associate Professor in May 1992, a full Professor in January
1993. He was promoted to be the head of the Department of Magnetism
and Magnetic Materialsand Ph.D supervisors in 1995, that of the
Department of Material Physics in 1997. He is the Advisory Board
Member of the Journal of Physics: Condensed Matters since Jan. 2000.
He was one of chair-Professors of the IMR from Mac. 1999 to Dec.
2003. He is currently the director of the Magnetism and Magnetic
Materials Division , Shenyang National Laboratory for Materials
¡¡¡¡Dr. Zhang Zhi-dong and his colleague
succeeded in synthesizing Sm-Fe-N magnets with high magnetic properties,
using mechanical alloying and hydrogenation processes. They investigated
systematically the structures and phase transitions of metastable
rare-earth phases. A breakthrough on the technique of preparing
ultra-high coercivity magnets lead to a world record of 96 kOe.
The spin configurations, spin waves and magnetic phase transitions
in a two-sublattice system, the spin waves in a multi-sublattice
system and superlattices were studied by analytical method and computer
simulation. The advances in understanding the mechanism of technologies
of magnetic treatments were great helpful for the project of application
of these technologies in Oilfields. He received several national
and CAS awards for either the natural sciences or the advance in
sciences and technology.
¡¡¡¡Recently, a great progress was made
in the light rare-earth giant magnetostrictive materials, the magnetic
ultrafine particles and nanocapsules, the exchange coupling and
quantum interference in magnetic thin films, the nanocomposite magnets
and giant magnetoresistance. More than six hundred papers has
been published in international journals, such as Nature, Adv. Mater.,
Adv. Funct. Mater, J. Amer. Chem. Soc., ACS Nano, Applied Physics Letters, Physical Review B, J. Physics and J. Applied
Physics, etc. One invited review article on the rare-earth metastable
phase was published in J. Phys. D Appl.Phys. Other eleven review
articles on the topics of the spin waves in magnetic thin films
and superlattices, the quantum interference in double quantum wells,
the magnetic nanocapsules, the new rare-earth intermetallics.
