Soft-landing techniques of radioactive probe atoms have been developed in the ASPIC facility which is installed at ISOLDE. The probe atoms were deposited at interfaces and on surfaces of metals and ferromagnets where they can be manipulated to occupy specific sites. Utilizing sensitive nuclear techniques for analysis, magnetic hyperfine fields and electric field gradients have been determined....

This talk reports on the results from the first electron emission channeling on-line run of the ECSLI collaboration, which took place during this year’s Mn beam time in June. Using our new on-line setup which is equipped with a position-sensitive Si pad detector with fast readout system and which was mounted on the LA2 beam line, two isotopes were successfully used for beta- emission...

Due to its high mobility of charge carriers, Ge is seen as an important material in future semiconductor technology. Despite the fact that this elemental semiconductor is known for a long time, the knowledge about the lattice location of impurities, the induced structural and electrical damage of Ge after ion implantation is relatively scarce.
Here we present a study of the lattice location...

This year the Physics Nobel Prize was awarded to Albert Fert and Peter Grunberg for the discovery of the magnetic effect of giant magnetoresistance, the basis of today’s magnetic recording in computer hard disks. This discovery is an example of using magnetism to control the electrical current flow through materials built at the nanometer scale. More recently, colossal magnetoresistance was...
