Dimerization transition in phenalenyl-based neutral radicals at high magnetic fields
We measured the anomaly in the specific heat due to the dimerization transition in ethyl and butyl phenalenyl-based neutral radical molecular conductors. A micro-calorimetric technique was used to measure samples in the hundred-microgram scale, in magnetic fields up to 15 T. Different field-dependen...

We measured the anomaly in the specific heat due to the dimerization transition in ethyl and butyl phenalenyl-based neutral radical molecular conductors.
