A device for generating and detecting a transient magnetization of a includes a static magnetic field generator configured to generate a static magnetic field of predetermined direction and strength at a sample location, a transmission device for providing a transient magnetic field at the sample location; and a receiving device for detecting a transient magnetization of the sample at the sample location. An LC oscillator forms both the transmission device and the receiving device. An oscillation frequency of the LC oscillator depends on a value of an inductive element of the LC oscillator. A controller configured to control the LC oscillator is connected, and a transient magnetic field can be generated by the LC oscillator and the controller that is capable of deflecting a magnetization of a sample out of equilibrium.

Device and method for generating and detecting a transient magnetization of a sample

A device for generating and detecting a magnetization of a sample includes a magnetic field generator configured to generate a static magnetic field of a predetermined direction and strength at a sample location, a transmitter configured to provide an additional magnetic field at the sample location, and a receiver configured to detect a magnetization of the sample. An assembly of at least two LC oscillators, the oscillation frequency of which is a function of a value of an inductive element of the LC oscillators and which are frequency-synchronized via a wiring, and forced by a control voltage to have a same oscillation frequency, is used as the receiver and/or the transmitter. A controller configured to control the assembly is connected, the assembly and the controller are configured to generate a magnetic field capable of deflecting a magnetization of the sample out of equilibrium.

Device for generating and detecting a magnetic resonance of a sample

A thin-film solar module contacted on one side includes a support layer, a photoactive absorber layer and at least one dopant layer deposited over a surface area of at least one side of the absorber layer so as to form a thin-film packet that is divided into thin-film solar cell areas by insulating separating trenches. The thin-film solar module includes first and second contact systems. The first contact system includes contacts connected by an outer contact layer. The second contact system consists of an inner contact layer covering a side of the solar cell areas that face away from the support layer so as to separately discharge excess charge carriers generated by incident light in the absorber layer. The second contact system includes structures that surround and electrically insulate the contacts, which extend through the inner contact layer from the outer contact layer. The first and second contact systems are electrically conductive and connected in series by series contacts in interconnection areas and electrically insulated from each other by an insulation layer outside of the interconnection areas.
