Due to the complex coupling of light with a magnetic sample, conventional MOKE magnetometers normally work by selecting a small range of incident wave-vector values, focusing the incident light beam to a small spot, and recording the reflected intensity at that angular range by means of photodetectors. Using this approach, additional methodologies and measurements are required for full vectorial magnetic characterization. Here, we computationally investigate a Fourier-space MOKE setup, where a focused beam ellipsometer using high numerical aperture optics and a camera detector is employed to simultaneously map the intensity distribution for a wide range of incident and reflected wave vectors. We employ circularly incident polarized light and no analyzing optics, in combination with a fitting procedure of the light intensity maps to the analytical expression of the Kerr effect under linear approximation. In this way, we are able to retrieve the three unknown components of the magnetization vector as well as the material' s optical and magneto-optical constants with high accuracy and short acquisition times, with the possibility of single-shot measurements. Fourier MOKE is thus proposed as a powerful method to perform generalized magneto-optical ellipsometry for a wide range of magnetic materials and devices. 000126822 536__ $$9info:eu-repo/grantAgreement/ES/DGA/Q-MAD$$9info:eu-repo/grantAgreement/EC/H2020/101001290/EU/3DNANOMAG-Three-dimensional nanoscale magnetic structures$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 101001290-3DNANOMAG$$9info:eu-repo/grantAgreement/ES/MICINN-AEI/PRTR-C17.I1 000126822 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000126822 590__ $$a3.2$$b2023 000126822 592__ $$a1.345$$b2023 000126822 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b201 / 439 = 0.458$$c2023$$dQ2$$eT2 000126822 591__ $$aPHYSICS, CONDENSED MATTER$$b31 / 79 = 0.392$$c2023$$dQ2$$eT2 000126822 591__ $$aPHYSICS, APPLIED$$b62 / 179 = 0.346$$c2023$$dQ2$$eT2 000126822 593__ $$aCondensed Matter Physics$$c2023$$dQ1 000126822 593__ $$aElectronic, Optical and Magnetic Materials$$c2023$$dQ1 000126822 594__ $$a6.3$$b2023 000126822 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000126822 700__ $$aHierro-Rodríguez, A. 000126822 700__ $$aSanz-Hernández, D. 000126822 700__ $$aSkoric, L. 000126822 700__ $$aChristensen, C.
