Experimental observations offerromagnetismin irradiated graphite point to the conclusion that sublattices of individual graphene layers in bulk graphite are populated by defects differently: that is, there must be a mechanism which makes the sublattices of graphene inequivalent. Such an intrinsic discrimina...

More recently, we computationally demonstrated the impor- tance of A-site cation ordering and Z parameter on the rock-salt layers where of n ¼ 1 RPs A ¼ Ca2 þ , inSrm2 þetalalincdLaBAaN2iþO4 with (ref. correlated 25). The electrons, ordering sequence of A-site cations ...
of the dopant cation. For example, for the Ba-end member (eight M3+dopants), the lowest energy Ga-hollandite configuration prefers Ga dopants stacked in adjacent layers, while the Al-hollandite prefers the Al dopants to be shifted in adjacent layers (Fig.3). The larger change in ionic ...

The structure at room temperature exhibits trigonal twin domains, each comprising a stacking-disordered sequence of distorted rocksalt-type slabs with variable thicknesses. Ge and Sb share the cation position and vacancies are partially ordered in defect layers (van der Waals gaps) between the slabs...
The Sm~(3+) and Ba~(2+) cations show a strong preference for distinct sites, with the majority of the larger Ba~(2+) cations situated in the perovskite block layers and Sm~(3+) cations predominantly in the rock salt layers. Magnetic susceptibility data demonstrate the strong ...
