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…
Unveiling unconventional magnetism at the surface of SrRuO
Rosalba Fittipaldi, Roman Hartmann, Maria Teresa Mercaldo +23
Materials with strongly correlated electrons exhibit physical properties that are often difficult to predict as they result from the interactions of large numbers of electrons comb…
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…
Unconventional Meissner screening induced by chiral molecules in a conventional superconductor
Hen Alpern, Morten Amundsen, Roman Hartmann +12
The coupling of a superconductor to a different material often results in a system with unconventional superconducting properties. A conventional superconductor is a perfect diamag…
