Imaging Topological Spin Structures Using Light-Polarization and Magnetic Microscopy

Abstract

We present an imaging modality that enables detection of magnetic moments and their resulting stray magnetic fields. We use wide-field magnetic imaging that employs a diamond-based magnetometer and has combined magneto-optic detection (e.g., magneto-optic Kerr effect) capabilities.

We employ such an instrument to image magnetic (stripe) domains in multilayered ferromagnetic structures.
