SYVC: Symposium Voltage Control of Functional Interfaces: Magneto-ionic Meet Memristive Systems

SYVC 1: SYVC: Voltage Control of Functional Interfaces – Magneto-ionic Meet Memristive Systems

Mittwoch, 14. März 2018, 15:00–18:00, H 0105

The control of functional material properties by an external voltage, as opposed to electric current based approaches, is intensely researched as a pathway to highly energy-efficient modern device operation. The magneto-ionic/electrochemical effect is a just emerging topic in the field of voltage controlled magnetic materials. In contrast to other magnetoelectric approaches, the magneto-ionic effect is based on ionic motion and electrochemical oxidation/reduction, and thereby allows to achieve large and non-volatile changes at room-temperature. However, the unambiguous identification of the microscopic origin is still challenging. The symposia gives an overview over magneto-ionic systems by covering both solid and liquid electrolyte-based architectures. Advanced interface-sensitive and in situ techniques that enable the investigation of the microscopic origin will be presented. A comparison with memristive/resistive approaches is made to elucidate differences and similarities in the underlying ionic mechanisms. The transfer to the tuning of other functional properties and from an interfacial effect to the control of bulk materials will be addressed to initiate a fruitful discussion about future key strategies.
