The Trotter theorem is applied to investigate the mixed-spin (1, 1/2) Heisenberg ferrimagnet chain with exchange anisotropy in a magnetic field. With the h... XY Chen,Q Jiang,YZ Wu - 《Solid State Communications》 被引量: 11发表: 2002年 The role of q-spin singlet pairs of physical...
Magnetorheological(MR) fluids are a class of new intelligent material whose rheological characteristics change rapidly in the presence of an applied magnetic field. The main characteristics and the operation modes of MR fluids have been analysed, the applications of MR fluids devices in engineering fiel...
To be used as a magnetic field sensor in different applications, the possibility of tuning the performance of the MTJ is important. Different means of tuning, such as voltage and magnetic field biasing, can be used. In this work, an external magnetic field from a permanent magnet was used ...
The magnetic properties were studied with a vibration magnetometer over the 4.2-300 k range at magnetic field strengths up to 8.10/sub 5/ A/m. The investigation showed that TiU/sub 2/S/sub 5/ is antiferromagnetic with temperature of 25 K, while ZrU/sub 2/S/sub 5/ and HFU/sub 2/S...
Monometalloporphyrin and p-oxo-bismetalloporphyrin compounds of metal iron,manganese and cobalt were synthesized, and used as the model compounds of cytochrome P-450 monooxygenase in catalytic oxidation of cyclohexane with iodosobenzene. The influence of the addition of magnetic field on the catalytic ...
One-dimensional (1D) nanocrystallites Ni fibers with different lengths were fabricated by the reduction of Ni2+ ions by hydrazine hydrate in the presence of external magnetic fields. The effect of the reaction conditions and magnetic field intensity on the microstructures and magnetic properties of ...
Because it represents a problem in the design of high-homogeneity magnets, we have been studying the magnetic properties of Ti alloys for their use instead of stainless steel as structural material for superconducting magnet construction. In this work, we present the comparative study of the ...
In order to characterize the magnetic properties of the above compound we performed the AC/DC magnetometry in the range 0-5 T. The special attention was paid to the phase transition at 7.9 K. The study in magnetic field supports magnetic ordering below 7.9 K....
