Abstract

We have found the pressure-induced (1) periodical down-up variation of transition temperature (T-c), (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 (T-c = 0.28 K) with spin polarizations on intermolecular contacts between the nitroxide oxygen and methyl hydrogen atoms (C-H . . .O-N contacts). These phenomena can be understood by the pressure-induced rotation of the methyl moiety relevant to the interaction-mechanism through C-H . . .O-N contacts. (C) 2001 Elsevier Science B.V.
