Imprinting properties of a magnetic dot array
into a superconductor
BASIC RESEARCH Issue Interplay between two
materials in close proximity, with antagonistic
properties Relevance Nanoscale interactions,
novel solid state devices System Array of
ferromagnetic nanodots covered with a
superconducting thin film. Method Resistivity
and magnetization vs. applied magnetic
field. Results Nanodots of carefully chosen
sizes exhibit a magnetic vortex state (see
upper panel). When covered by a superconducting
film, this system shows hybridized properties a
superconducting transition, hysteresis and
remanence. For a fixed field there are two very
different resistivities (lower panel) depending
of the magnetic history. This artificially
induced behavior leads to a novel, extremely high
magnetoresistance.

DESCRIPTION
A 27 minute TV program was produced which
explains difficult concepts from Nanoscience to
the general public. Explanations of
nanofabrication, quantum mechanical tunneling,
and magnetism are presented in a humorous and
entertaining fashion
