Abstract

We have found the pressure-induced (1) periodical down-up variation of transition temperature (Tc), (2) ferro- to antiferro-magnetic transition and (3) reduction of the magnetic lattice dimensionality in a genuine organic crystalline bulk-ferromagnet p-Cl-C6H4-CH=N-TEMPO (Tc=0.28 K) with spin polarizations on intermolecular contacts between the nitroxide oxygen and methyl hydrogen atoms (C-HO-N contacts). These phenomena can be understood by the pressure-induced rotation of the methyl moiety relevant to the interaction-mechanism through C-HO-N contacts.
