	1	Magnetic properties of perpendicularly orientated L1_0 FePt nanoparticles显示文摘L10 FePt films were deposited on MgO (001) substrates heated to 700°C by magnetron sputtering.Assisted by the misfit of lattice between film and substrate,strong (001) texture was formed.The film at nominal thickness t N=5 nm was composed of nanoparticles with a size of~70 nm,and showed a high coercivity of~105 kOe at 4.2 K.At t N=~50 nm,as the film changed from discontinuous to continuous,the coercivity dropped about one order of magnitude.Micromagnetic simulation implies that the magnetization reversal is a vortex-like nuclear type.The ideal coercivity of a separated single-domain L10 FePt nanoparticle with a size of 70 nm×70 nm×5 nm is~121 kOe.This tells us that the experimental coercivity has nearly reached the limit of ideal single crystalline nanoparticles.

	2	Effect of Phosphor Addition on Intergranular Exchange Coupling of Co-Pt Thin Films显示文摘In this paper, ternary Co-Pt-P thin films were prepared by magnetron sputtering with platinum and home-made Co-P chips pasted on the cobalt target. The structure and magnetic properties were investigated by X-ray diffraction (XRD) and vibrating sample magnetometer (VSM), respectively. With increasing phosphor content, the coercivities of Co-12 at.% Pt-P films increase from 1034 to 1525 Oe owing to the exchange decoupling among magnetic grains. The decrease of inter-granular exchange coupling was confirmed by delta-M curve measurement and magnetic force microscopy (MFM). Transmission electronic microscopy (TEM) with nano- beam composition analysis shows that phosphor segregated at cobalt-based grain boundaries is responsible for the exchange decoupling. It is thus suggested that the phosphor addition is e?ective to tune the exchange coupling of magnetic grains, particularly for perpendicular recording media.

	3	Ll_0 FePt thin films with 001crystalline growth fabricated by ZnO addition and rapid thermal annealing显示文摘FePt films with a high degree of order S of the L1 0 structure (S > 0.90) and well defined 001crystalline growth perpendicular to the film plane are fabricated on thermally oxidized Si substrates by the addition of ZnO and a successive rapid thermal annealing (RTA) process. The optimum condition to prepare high-ordering L1 0 FePtZnO films is 20 vol% ZnO addition and 450℃annealing. The effect of the ZnO additive on the ordering process of the L1 0 FePtZnO films is discussed. In the annealing process, Zn atoms move to the film surface and evaporate. The motion of the Zn atoms accelerates the intergrain exchange and decreases the ordering temperature.	刘曦 Ishio Shunji	2013	Chinese Physics B2013，22，8：	0
