We know that this is the right way to look at it because firstly switching lensing on and off in the difference spectra for this case has only very little impact, and secondly

As anisotropy axes establish preferential directions for the magnetic moments to sit on, reversing the magnetization of a systems necessarily implies over- coming the extra

As a strong field ligand, CO affects the magnetic state of MnPc in two ways: (i) it increases the splitting of the d orbitals, and thus favors the low spin configuration in the

The region of those nuclei, the ground state of which is dominantly an intruder configuration while their normal configuration ground state is found as an excited state, is called

MD simulations in this and previous work has allowed us to propose a relation between the nature of the interactions at the interface and the observed properties of nanofluids:
