Topography-based navigation in a millikelvin scanning tunneling microscope using binary-encoded position markers
R. Fischer-SüÃlin, R. Hartmann, T. Kandra +1
We present a compact millikelvin scanning tunneling microscope (STM) operating at 270mK with topographic navigation to micron-scale targets. Two piezoelectric low-temperature nanop…

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…

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…
