題名: | Magnetization reversal characteristics in NiFe elliptical ring arrays | 作者: | 李尚凡 Chang,Liang-Juan ;Chen,Kuan-Yu ; Lin,Lu-Kui ; Yao,Yeong Der ; Lin,Pang ; Lee,Shang Fan |

The magnetic field was applied parallel or perpendicular to the long axis. The magnetization hysteresis loops showed a simultaneous-reversal single-step transition or two-step transition involving flux closure vortex states. For various aspect ratios and thicknesses, the transition between single-step and double-step magnetization reversals was measured to form phase diagrams. Simulations of the magnetization reversal behavior agreed with our results. | 關聯: | IEEE Trans. Magn.,46(6),1975-1977 | 資料類型: | article |
