AO-HDS has been mainly explained by helicity-dependent heating effect due to magnetic circular dichroism. On the contrary\, tran sfer of photonic angular momentum to magnetization in AO-HDS has also been discussed [4\, 5]\, which is promising towards ultrafast optical manipula tion of magnetization. Recently\, helicity-dependent magnetization dynamic s induced by circularly-polarized light via a stroboscopic measurement has been reported in ferromagnetic thin films and ferromagnet/ heavy metal he terostructures [6-10]\, which enables us to quantify transfer of photonic angular momentum to magnetization of ferromagnetic thin film. Electronic s pin and orbital angular momentum induced by spin angular momentum of light give rise to angular momentum transfer torque on magnetization. Quantitat ive consideration of the angular momentum conversion will be discussed in the presentation.\n\nRoom: 4-A014\, Bldg: Institut Jean Lamour \, 5 Allee Guinier\, Nancy\, Lorraine\, France\, 54011 LOCATION:Room: 4-A014\, Bldg: Institut Jean Lamour \, 5 Allee Guinier\, Nan cy\, Lorraine\, France\, 54011 ORGANIZER:stephane.mangin@univ-lorraine.fr SEQUENCE:10 SUMMARY:Magnetization dynamics induced by circularly-polarized light ~ Tran sfer of photonic spin angular momentum to magnetization ~ URL;VALUE=URI:https://events.vtools.ieee.org/m/489444 X-ALT-DESC:Description: <br /><p class="MsoNormal"><span lang="EN-US">Durin g the last decade\, it has been demonstrated that magnetization of thin fi lm metallic ferromagnets can be reversed by irradiation of circularly-pola rized light and magnetization directions are determined by the light-helic ity\, referred to as all-optical helicity-dependent switching (AO-HDS) [1- 5].
