From Film to Flakes: Electronic Properties and Magnetization Variations in Yttrium Iron Garnet
Pia M. Düring, Seema, Roman Hartmann +7
Yttrium iron garnet (YIG) is a ferrimagnetic insulator valued for its high Curie temperature, very low magnetic damping, and ability to support long-range spin-wave transport. Thes…
Spatial mapping of magnetization fluctuations via time-lapse Kerr microscopy
Xian-Yue Ai, Ivan Soldatov, Leon Oleschko +5
Combining wide-field magneto-optical Kerr microscopy with a time-lapse analysis scheme allows investigating magnetization fluctuations with high spatial as well as temporal resolut…
Single-crystalline YIG flakes with uniaxial in-plane anisotropy and diverse crystallographic orientations
Roman Hartmann, Seema, Ivan Soldatov +12
We study Y3Fe5O12 (YIG) flakes that we produce via mechanical cleaving and exfoliation of YIG single crystals. By characterizing their structural and magnetic properties, we find t…
Magnetic domains in ultrathin, bulk-like and proximity-coupled Europium Oxide
Seema, Moumita Kundu, Paul Rosenberger +3
The control of electron spins in materials that are simultaneously ferromagnetic and insulating opens up a wealth of quantum phenomena in spin-based electronics. Thin films of euro…
