Geometrical frustration occurs when entities in a system, subject to given lattice constraints, are hindered to simultaneously minimize their local interactions. In magnetism, systems incorporating geometrical frustration ...

Geometrical frustration in either classical or quantum lattice systems is a phenomenon in which the impossibility of satisfying simultaneously all constraints of the system Hamiltonian leads to complex structures with ...

Defective zinc ferrites ZnFe$_2$O$_{4-δ}$ obtained by vacuum annealing bulk Zn-ferrite at different temperatures TAnn were investigated by using XANES at Zn-K, Fe-K and XMCD at Fe-L$_{2,3}$ edges, static and dynamic magnetic ...
