Mechanism of magnetization enhancement at CoO/permalloy interfaces

Reversible electric-field control of magnetization at oxide interfaces.

Electric-field control of magnetism has remained a major challenge which would greatly impact data storage technology. Although progress in this direction has been recently achieved, reversible magnetization switching by an electric field requires the assistance of a bias magnetic field. Here we take advantage of the novel electronic phenomena emerging at interfaces between correlated oxides an...

Suppressed magnetization at the surfaces and interfaces of ferromagnetic metallic manganites.

What happens to ferromagnetism at the surfaces and interfaces of manganites? With the competition between charge, spin, and orbital degrees of freedom, it is not surprising that the surface behaviour may be profoundly different to that of the bulk. Using a powerful combination of two surface probes, tunnelling and polarized x-ray interactions, this paper reviews our work on the nature of the el...

Temperature dependence of magnetization-induced second harmonic generation at buried exchange-biased interfaces

The mechanism of cAMP-mediated enhancement at a cerebellar synapse.

Increases in cAMP have been shown previously to enhance the strength of the granule cell to Purkinje cell synapse. We have examined the mechanisms underlying this enhancement in rat cerebellar brain slices. Elevation of cAMP levels by forskolin increased synaptic currents in a dose-dependent manner. Fluorometric calcium measurements revealed that forskolin did not affect presynaptic calcium inf...
