Method for labeling, verification and/or identifying and device for implementing the method
First Claim
1. A method of labeling, authenticating and/or identifying an object using mixed electron nuclear resonances, comprising:
- applying a minor, labeling amount of at least one mixed electron nuclear resonant material to the object;
providing a detection system emitting radio frequency energy in a non-cryogenic detecting volume, and spectroscopically detecting radio frequency responses from the detecting volume;
placing the labeled object in the detecting volume for detection of the material without applying a static field in the detecting volume; and
selecting for the material a substance resonating with a radio frequency response under non-cryogenic conditions, where the radio frequency response is large enough at zero external static field for a minor labeling amount of the selected substance to be detectable on the object.

Abstract
A method of labeling, authenticating and/or identifying a paper, credit/identification card, bank note, article or any other object using both nuclear magnetic resonance in magnetically ordered materials and nuclear quardrupole resonance phenomena as well as other phenomena of electric/magnetic dipole or tunnel transitions between Stark-Zeeman sub-levels, frequencies of which belong to the radio-frequency band. A minor amount of at least one authenticating substance is added to the object, the substance having a strong unique and identifiable response in radio-frequency domain at room temperature, with the spectroscopy being performed in the absence of any supported external static field, and with any specific response (intensity, line width, line shape, splittings, free induction decay, spin echoes or their combinations) being used as a criterion for discrimination.

41. A method of labeling, authenticating and/or identifying an object using mixed electron nuclear resonances, comprising:
-
applying a minor, labeling amount of at least one mixed electron nuclear resonant material to the object; providing a detection system with a probe head or coil continuously emitting radio frequency energy in a non-cryogenic detecting volume, and spectroscopically detecting radio frequency radiation emitted or absorbed from the detecting volume; placing the labeled object in the detecting volume for detection of the material without applying a static field in the detecting volume; selecting for the material a substance resonating with a radio frequency response under non-cryogenic conditions, where the radio frequency response is large enough at zero external static field for a minor labeling amount of the selected substance to be detectable on the object; wherein the emitted radiation further includes emission at multiple non-working frequencies different than the resonant frequency, thereby masking the identity of the working resonant frequency.
