Appearance of ferromagnetism in Pt(100) ultrathin films originated from quantum-well states
Tatsuru Yamada, Keisuke Ochiai, Hirofumi Kinoshita +5
Ferromagnetism was observed in a Pt(100) ultrathin film deposited on a SrTiO3(100) substrate. The ferromagnetism, which appears in films with thicknesses of 2.2-4.4 nm, periodicall…
Interfacial-hybridization-modified Ir Ferromagnetism and Electronic Structure in LaMnO/SrIrO Superlattices
Yujun Zhang, Yong Zheng Luo, Liang Wu +19
Artificially fabricated 3/5 superlattices (SLs) involve both strong electron correlation and spin-orbit coupling in one material by means of interfacial 3-5 coupling, w…
Giant perpendicular magnetic anisotropy in Ir/Co/Pt multilayers
Yong-Chang Lau, Zhendong Chi, Tomohiro Taniguchi +8
We have studied the magnetic properties of multilayers composed of ferromagnetic metal Co and heavy metals with strong spin orbit coupling (Pt and Ir). Multilayers with symmetric (…
Ultrafast demagnetization of Pt magnetic moment in L1-FePt probed by hard x-ray free electron laser
Kohei Yamamoto, Yuya Kubota, Motohiro Suzuki +15
We demonstrate ultrafast magnetization dynamics in a 5d transition metal using circularly-polarized x-ray free electron laser in the hard x-ray region. A decay time of light-induce…
Enhanced spin-orbit torque via interface engineering in Pt/CoFeB/MgO heterostructures
Hae-Yeon Lee, Sanghoon Kim, June-Young Park +9
Spin-orbit torque facilitates efficient magnetization switching via an in-plane current in perpendicularly magnetized heavy metal/ferromagnet heterostructures. The efficiency of sp…
Electric-field-induced changes of magnetic moments and magnetocrystalline anisotropy in ultrathin cobalt films
Takeshi Kawabe, Kohei Yoshikawa, Masahito Tsujikawa +10
In this study, the microscopic origins of the voltage-controlled magnetic anisotropy (VCMA) in 3d-ferromagnetic metals are revealed. Using in-situ X-ray fluorescence spectroscopy t…
Detection of induced paramagnetic moments in Pt on YFeO via x-ray magnetic circular dichroism
Takashi Kikkawa, Motohiro Suzuki, Jun Okabayashi +4
Magnetic moments in an ultra-thin Pt film on a ferrimagnetic insulator YFeO (YIG) have been investigated at high magnetic fields and low temperatures by means of X-r…
Microscopic Origin of Interfacial Dzyaloshinskii-Moriya Interaction
Sanghoon Kim, Kohei Ueda, Gyungchoon Go +15
Chiral spin textures at the interface between ferromagnetic and heavy nonmagnetic metals, such as Neel-type domain walls and skyrmions, have been studied intensively because of the…
Quadrupole moments in chiral material DyFe3(BO3)4 observed by resonant x-ray diffraction
Hiroshi Nakajima, Tomoyasu Usui, Yves Joly +4
By means of circularly polarized x-ray beam at Dy L3 and Fe K absorption edges, the chiral structure of the electric quadrupole was investigated for a single crystal of DyFe3(BO3)4…
