Inductive array, oscillator assembly, device, and method for generating and/or detecting a magnetization of a sample

An apparatus for generating and/or detecting a magnetization of a sample, comprising:

• an oscillator arrangement comprising a plurality of inductive assemblies, each inductive assembly of the plurality of inductive assemblies comprising a plurality of interconnected inductive segments,
• wherein, in an inductive assembly of the plurality of inductive assemblies, each inductive segment of the plurality of inductive segments includes an inductive element and a connection circuit, which is electrically connected to the inductive element, for electrically connecting to an adjacent inductive segment,
• wherein inductive assemblies of the plurality of the inductive assemblies are connected to each other in a frequency-synchronized manner,
• wherein the inductive element and the connection circuit of a common inductive segment are formed in a common integrated circuit, and
• wherein, in each inductive assembly of the plurality of inductive assemblies, the inductive segments are connected to each other in an at least substantially annular, self-contained series arrangement;
• and
• a sample location.

A method or generating and/or detecting a magnetization of a sample at a sample location, for electron spin resonance spectroscopy or nuclear magnetic resonance spectroscopy, comprising the steps of:

• providing at least one inductive assembly having a plurality of interconnected inductive segments that are connected to each other in an at least substantially annular, self-contained series arrangement,
• wherein each inductive segment, of the plurality of inductive segments, includes an inductive element and a connection circuit, which is electrically connected to the inductive element, for electrically connecting to an adjacent inductive segment, and wherein the inductive element and the connection circuit of each common inductive segment are formed in a common integrated circuit;
• providing a magnetic field (B0) in a predetermined direction and of a predetermined strength at the sample location;
• and
• operating the at least one inductive assembly to perform at least one of (i) provide an additional magnetic field (B1) at the sample location, and (ii) to detect a magnetization of the sample at the sample location.
