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.
