Characteristics of sound field and temperature field, and the relation between the width of coupling layer, the size and the position of treated area are presented.

Cu doping effect on the interlayer coupling and negative MR of Fe/Si multilayers;

Study of interlayer coupling and magnetic properties in Fe-Ni/Cu multilayers;

Magnetic properties were evaluated by VSM and spin valve magnetoresistance was investigated by a four-probe method to study the interlayer coupling of the two magnetic layers.

Considering the interface couplings (ferromagnetic coupling and antiferromagnetic coupling),the spin-wave dispersion relations,wave forms and resonant spectra in ferromagnetic bilayers are studied.

It is shown that there must exist acoustic-acoustic interface spin waves for anti-ferromagnetic interface coupling.

The stronger the ferromagnetic interface coupling,the highter the energy of A OISW,but the st.

Research purpose: In view of the problem of construction time limited and the construction passage limited of underground factory house for Hainan construction project, we bring up a new construction technology-several layers excavating and stress discharging in advance to solve this difficult problem.

The interlayer magnetic couplings and the magnetic-moment distributions as a function of the number of Cr spacer are investigated systematically by using plane-wave pseudopotential method based on density functional theory.
