Abstract
A magnetic material is constituted of a ferromagnetic or ferrimagnetic insulator in a double perovskite structure of SrAOsBO(0.5≤x≤0.5, −0.5≤y≤0.5). A is an alkali metal or alkaline earth metal atom, and B is a transition metal atom, alkali metal atom, or alkaline earth metal atom). The insulator may be SrOsO, where x=y=0 in the above formula. SrOsOis formed to have a cubic crystal structure where strontium atoms, osmium atoms, and oxygen atoms are arranged at lattice points.
