Experimental evidence of the dependence of spin tunnelling on the concentration of dislocations in Mn12 crystals
F. Torres, J. M. Hernandez, E. Molins +2
We present experimental results on resonant spin tunnelling in a single crystal of Mn-2Cl benzoate with different concentration of dislocations. The time evolution of the ma…
