Zhao, Fei; Li, Zai-Dong; Li, Qiu-Yan; Wen, Lin; Fu, Guangsheng; Liu, W. M. Magnetic rogue wave in a perpendicular anisotropic ferromagnetic nanowire with spin-transfer torque. (English) Zbl 1252.82131 Ann. Phys. 327, No. 9, 2085-2095 (2012). Summary: We present the current controlled motion of a dynamic soliton embedded in a spin wave background in ferromagnetic nanowire. With the stronger breather character, we get a novel magnetic rogue wave and clarify its formation mechanism. The generation of a magnetic rogue wave mainly arises from the accumulation of energy and magnons toward its central part. We also observe that the spin-polarized current can control the exchange rate of magnons between the envelope soliton and the background, and the critical current condition is obtained analytically. Even more interesting is that the spin-transfer torque plays the completely opposite role for the cases below and above the critical value.
