摘要
New results of quasi-elastic neutron scattering on the one-dimensional antiferromagnet TMMC establish that below 5 K TMMC is actually in an XY state. The effect of a magnetic field is described in terms of crossover transitions associated with a reduction of the spin dimensionality. TMMC undergoes an XY-Ising transition when H is applied perpendicular to the chain axis. © 1979.
