Abstract The strong electron paramagnetic resonance (EPR) of polarized targets can be used to search for axions as dark matter candidates in the range of (1–100) GHz. Once the axions are absorbed they can provide the communications gate for spin thermal contact between different nuclei that were kept artificially at different temperatures.

Abstract In an applied microwave field, the free electron spin-spin interaction reservoir in polarized target material couples strongly to the Zeeman interaction reservoirs of different nuclei. This leads to an effective cross-relaxation between different nuclei, which was studied at different levels of microwave power between protons and 13 C nuclei in the large SMC target using butanol as material.

The time constants τ of the spin coupling between protons and 13C‐nuclei in the SMC butanol target was measured as a function of the applied microwave power. A clear decrease of τ in the presence of a microwave field was found. This has to be related to the cross‐relaxation between the different spin species. The application for cold dark matter detection is outlined.
