Designer Magnetoplasmonics with Nickel Nanoferromagnets
Artikel i vetenskaplig tidskrift, 2011
We introduce a new perspective on magnetoplasmonics
in nickel nanoferromagnets by exploiting the phase tunability of the optical polarizability due to localized surface plasmons and simultaneous magneto-optical activity. We demonstrate how the concerted action of nanoplasmonics and magnetization can manipulate the sign of rotation of the reflected light’s polarization (i.e., to
produce Kerr rotation reversal) in ferromagnetic nanomaterials and, further, how this effect can be dynamically controlled and employed to
devise conceptually new schemes for biochemosensing.
