Spin Caloritronics

February 9-13, 2009


“Spintronics” is the science and technology of harnessing the electron spin degree of freedom in circuits and devices in order to realize new or improved technological functionalities. The focus of attention in “Caloritronics” is the control of temperature gradients and the corresponding thermoelectric phenomena in small structures. “Spin Caloritronics” is defined by the intersection of both fields.

The international community interested in this emerging field is still rather small and we were happy to have been able to attract practically all main players from Europe, the US, China and Japan, with more than 50 participants each day.

The workshop was organized in terms of topical session with invited expert speakers, followed by discussion sessions introduced and moderated by selected leading scientists. The workshop started by focusing on novel effects, such as spin-related thermoeletric effects. The interpretation of the recently discovered Spin Seebeck effect excited lively discussions. Special focus was directed as well to the zoology of Hall effects due to thermal current flow, such as the anomalous and spin Nernst, Ettingshausen and Righi-Le Duc effects. Other topical/discussion sessions were devoted to materials and devices. The workshop was wrapped up on the last day by extended discussion sessions devoted to experimental and theoretical developments of the field.

The workshop created significant synergy between the fields of spintronics, electron device physics, materials science, and energy research, between experiment, theory, and computational physics. It stimulated new ideas and collaborations. There was a consensus that the progress in the field should be monitored by subsequent follow-up conferences. At present, the possibilities are being investigated to fund Spin Caloritronics II in Japan in early spring of 2010.

The stark beauty of the lake district around Leiden during a crisp winter afternoon pleasantly surprised the participants (even those from the Netherlands).

All participants have been in awe of the high quality of the Lorentz Center’s premises and expressed their gratitude for the excellent support by the highly motivated staff. We gratefully acknowledge the financial support by the Lorentz Center, the IMR and the Kavli Institute of NanoScience Delft.
