- Abstract
- Magnetic properties can be manipulated to enhance certain functionalities by tuning different
material processing parameters. Here, we present the controllable magnetization steps of hysteresis
loops in double-perovskite single crystals of Eu2CoMnO6. Ferromagnetic order emerges below
TC ? 122 K along the crystallographic c axis. The difficulty in altering Co2+ and Mn4+
ions naturally induces additional antiferromagnetic clusters in this system. Annealing the crystals in different gas
environments modifies the mixed magnetic state, and results in the retardation (after O2- annealing)
and bifurcation (after Ar-annealing) of the magnetization steps of isothermal magnetization. This
remarkable variation offers an efficient approach for improving the magnetic properties of doubleperovskite
oxides.
