中文拼音 [náncíhuàfāngxiàng]
難磁化方向
英文
direction of hard magnetization-
It is the main purpose of this paper to calculate the energy splitting of ground state and excited states induced by thermally assisted quantum tunneling. first, a brief introduction is given for the theoretical and experimental studies on the magnetic macroscopic quantum effects. then, spin tunneling in a uniaxial ferromagnetic particle in transverse magnetic field is converted to a pseudoparticle moving in effective double - well potential with the help of the effective potential description of quantum spin systems developed by ulyanov and zaslavskii. finally using the periodic instanton method we evaluate the transition amplitude, energy shift and prefactor of wkb exponential and the energy splitting of ground state and the tunneling rate for excited states induced by thermally assisted quantum tunneling are obtained
文章首先對磁性宏觀量子效應的理論和實驗方面作了簡單介紹，然後藉助于ulyanov和zaslavskii發展的一種等效勢描述方法，把外磁場沿難磁化軸方向時的自旋隧穿約化成在等效雙勢阱中運動的粒子，利用瞬子方法給出基態能級劈裂，最後利用周期瞬子方法分別計算了隧穿幅、能級移動以及wkb前因子，從而給出由於熱助量子隧穿引起的激發態的隧穿率。Present status and development orientation of magnetization roasting technology for refractory red iron ores
難選紅鐵礦磁化焙燒技術現狀及發展方向If the magnetic anisotropy of the magnetostrictive layer is much larger than that of the soft layer, the magnetic hysteresis and magnetostriction of the ecmm magnetized along the easy axis of the magnetostrictive layer are different from those of hard axis of the magnetostrictive layer
當磁致伸縮層磁各向異性與軟磁層磁各向異性相差較大時，沿磁致伸縮層的易軸方向或難軸方向磁化，多層膜的磁學及力學性質差別較大。A better low - field magnetostrictive sensitivity has been obtained when the ecmm is magnetized along the hard axis of the magnetostrictive layer
