Shift of the blocking temperature of Co nanoparticles by Cr capping

We have studied the effect of Cr capping on the magnetic properties of Co nanoparticles (NPs). The NPs have an average diameter of 2.2 nm. The blocking temperature TB of the bare Co particles is 13.2 K. By capping with a thin Cr layer up to a thickness of tCr = 0.52 nm, we first observe a decrease o...
