The main focus of the research utilizing the requested instrument is to study spatially and time resolved magnetization dynamics in antiferromagnets in which emergent optical, electrical and thermal magnetotransport phenomena arise due to particular crystal and magnetic lattice symmetries. We will develop various methods to exploit these magnetotransport effects for measuring the ultrafast exchange enhanced magnetisation dynamics. The requested instrumentation comprises a low-vibration magnetooptical cryostat with high spatial resolution scanning ability and electrical access up to microwave frequencies including a large magnetic vector field and combined with a high energy fs- pulse laser system.
