Device for generating and detecting a magnetic resonance of a sample

A device for generating and detecting a magnetization of a sample, the device comprising:

• 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,
• wherein 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,
• wherein a controller configured to control the assembly is connected,
• wherein the assembly and the controller are configured to generate a magnetic field capable of deflecting a magnetization of the sample out of equilibrium,
• wherein the sample location lies in a near field of the assembly,
• wherein a demodulator, and analog-to-digital converters as well as a digital data processor are connected downstream of the assembly for processing an output voltage of the assembly,
• wherein a spectral component determiner configured to determine spectral components of the magnetization of the sample and the spin concentration of individual spectral components to be determined therefrom and an output configured to output the magnetization are provided in the digital data processor
• wherein one of the LC oscillators in the assembly is executed as a voltage-controlled oscillator and a phase locked loop is connected, so that all LC oscillators in the assembly follow the reference frequency.
