Researchers have discovered that light – in the form of a laser – can trigger a form of magnetism in a normally nonmagnetic material. This magnetism centers on the behavior of electrons...

An Unusual Magnetic effect found in Nanolayers of an oxide of Lanthanum & Manganese (LaMnO3)

The research revealed an abrupt magnetic transition brought about by the slightest change in thickness of the layer. Materials with exceptional electronic and magnetic properties are of great importance for many apps. A particularly versatile class of materials are the ‘perovskite oxides’.
Twente University researchers have discovered a special effect relating to the magnetism of one of such perovskite-oxides; lanthanum-manganese-oxide. This material consists of stackings of LaMnO3 unit cells, quite comparable to stacking of LEGO but the building blocks are only 0.4nm in size.
The new discovery is that the magnetism in these layers is switched on abruptly when the number of LaMnO3 building blocks changes from 5 to 6...
