Slow magnetic relaxation and hysteresis effects of dynamic origin have been observed above liquid helium temperature in a chain compound (see picture), comprising ConII centers and organic radicals, without any evidence of phase transition to three-dimensional magnetic order. These results are the first evidence of the slow dynamics predicted for one-dimensional magnetic systems with Ising anisotropy, and they open the possibility of storing information in a single magnetic nanowire.

Abstract

Slow magnetic relaxation and hysteresis effects of dynamic origin have been observed above liquid helium temperature in a chain compound (see picture), comprising ConII centers and organic radicals, without any evidence of phase transition to three-dimensional magnetic order. These results are the first evidence of the slow dynamics predicted for one-dimensional magnetic systems with Ising anisotropy, and they open the possibility of storing information in a single magnetic nanowire.
