*SEMINARIOS DEL IFLP y DEL DEPARTAMENTO*

* MARTES 1° de NOVIEMBRE / 11 hs / AULA CHICA*

*"The magnetism of oxides"*

* EXPONE: Josep Fontcuberta- Institut de Ciència de Materials de
Barcelona
(ICMAB-CSIC)*

 Magnetite Fe3O4 guided the humankind towards unknown frontiers. Since
those early days, oxides have been the backbone of many scientific and
technologic developments and reached a peaceful maturity, robustly
settled
in textbooks and deeply integrated in technological applications, until
late 1980's when the high temperature superconductors were discovered.
The
subsequent rush stimulated an impressive development in oxide thin film
growth technologies and a deep revision of the understanding of metal
oxides and strongly correlated electronic systems which ultimately
boosted
a tremendous explosion of research on oxides. Today, long beyond the
celebrated colossal magnetoresistance, oxides are fuelling the discovery
and development of unexpected, intriguing and fascinating new areas of
knowledge, such as magnetic ferroelectrics and magnetic monopoles.
Ferromagnetic oxides are finding its way as active components in
spintronics, either as spin filters for advantageous magnetic tunnel
junctions or used to manipulate spins in nonmagnetic materials, which
could
eventually lead to pure spin-current based rather than charge&spin-based
devices, with prospects of more energy-efficient spintronic devices. The
tinny spin-orbit coupling interaction, responsible for the magnetic
anisotropy, has also emerged as a fundamental interaction allowing to
modulate electric transport properties, not only of metallic
ferromagnetic
systems but also in antiferromagnetic metals and insulators that may
lead
to a new generation of magnetic memories. Still, "interface is the
device"
and interfaces between oxides and metals and interfaces between large
band-gap oxides have led to the discovery of emerging properties such as
switchable "on-off" magnetization or magnetism and superconductivity
that
challenges our understanding of oxides. This is the playground where we
happily play, learn and envision the future while enjoying building a
new
science out of the old good oxides. Along the seminar, we will jointly
follow the track of the new materials and ideas that make this journey
possible and so successful.
