Effect of magnetization on exchange biasing in Co-Ni/FeMn bilayers;

Energy spectrum and magnetization of single electron quantum dot in a periodic magnetic field;

Discover as a result:(1)though the absorption coefficient and laser brief strength is less in steam-ion mix area.

The strength weakening controlling mechanism of rock bursts in coal mines was put forward.

The test results reveal that the excessive settlement and lateral movement of the caissons are due to strength weakening of soft clay during the strong storm.

The results show that the excessive settlement and lateral movement of the caissons are due to the strength weakening of the soft clay during the strong storm,and also show that the ability of the s.

The magnetization intensity, residual magnetization intensity and coercitive force of electroless Co-Ni-B and Co-Ni-B-La alloy films were compared.

They have discussed the influence of damping parameter and temperature on the relaxation of particle magnetization intensity.

the border relation of polarization intensity and magnetization intensity have been delivered with a method which differs from general electrodynamics literature and bases on microcosmic physical medium model, and this method is in favor of understanding and boundary value relation from point of view of microcosm.
