A magnetic element may generally be configured at least with a magnetic stack having a multilayer barrier structure disposed between first and second ferromagnetic layers. The multilayer barrier structure can have a binary compound layer disposed between first and second alloy layers with the binary compound having a metal element and a second element where at least one alloy layer has the metal element and a third element dissimilar from the second element.
