“…Simulations suggest that the magnetization reversal is not realized via precession, but is caused by a linear process in which the magnitude of the magnetization passes through zero, in the presence of magnetic fields of ∼20 T. 4,5 The magnetization dynamics can also be triggered by light that is linearly polarized in a direction noncollinear to the crystal axis. 6,7 For a comprehensive review on ultrafast all-optical magnetization dynamics, see Ref. 8.…”

We investigate the nonresonant all-optical switching of magnetization. We treat the inverse Faraday effect (IFE) theoretically in terms of the spin-selective optical Stark effect for linearly or circularly polarized light. In the dilute magnetic semiconductors (Ga,Mn)As, strong laser pulses below the band gap induce effective magnetic fields of several teslas in a direction which depends on the magnetization direction as well as the light polarization and direction. Our theory demonstrates that the polarized light catalyzes the angular momentum transfer between the lattice and the magnetization.

“…Controlling the magnetization dynamics with femtosecond laser pulses is a rapidly developing area of research [1]. Among the various mechanisms responsible for the excitation of such dynamics, the nonthermal ones are the most interesting [2][3][4][5][6][7][8][9]. Using nonthermal excitation one is able to introduce changes in the magnetic system at very short time scales, which are defined by the spin-orbit coupling (∼1-10 ps) and not by thermalization processes (10-1000 ps).…”

“…The first type is characterized by an impulsive action, that only exists during the laser pulse. Inverse Faraday [3] and Cotton-Mouton [7,10] effects (IFE and ICME) are representative of this type. The second type are displacive effects such as the photoinduced change of magnetic anisotropy (PIA) [5,11], which persist in the sample for a time interval much longer than the length of the laser pulse.…”

Excitation of magnetic precession in bismuth iron garnet via a polarization-independent impulsive photomagnetic effect

et al. 2015

View full text Add to dashboard Cite

A polarization independent, non-thermal optical effect on the magnetization in bismuth iron garnet is found, in addition to the circular polarization dependent inverse Faraday effect and the linear polarization dependent photo-induced magnetic anisotropy. Its impulsive character is demonstrated by the field dependence of the amplitude of the resulting precession, which cannot be explained by a long living photo or heat induced anisotropy.

Laser-induced ultrafast spin manipulations in positively charged two-magnetic-center molecular ions with a small number of bridging atoms are investigated to explore the role of bridging atoms in the spin switching process and spin transferability between the magnetic centers via the Λ process. Taking O and Mg as examples for bridging atoms, fully ab initio calculations demonstrate that spin flip can be readily achieved on subpicosecond time scales at both magnetic centers of the linear structures composed of two nonidentical magnetic atoms with a single bridging atom in between. Although these two nonmagnetic elements possess completely different chemical and electronic natures, both types of bridging atoms contribute to spin density redistribution at the magnetic atoms, especially for the low-lying triplet states that are suitable to act as initial and final states in the Λ-type process of spin flip or transfer. This also provides a rule-of-thumb that spins in the linear structures can be flipped more easily since symmetric structures exhibit weaker magnetocrystalline anisotropy. The spin transfer process achieved in the structure [Fe-O(Mg)-Co] + demonstrates that if both bridging atoms are involved to further lower the symmetry of the linear structures, spin transferability between the Fe and Co atoms can be improved.
