While bulk YCo2 is paramagnetic in nature, the thin films of YCo2 (111) have an intriguing feature of surface magnetism, with magnetization localized on Co atoms near the surface. Using the density functional based approach we show that the surface magnetization per Co atom can be increased slightly by applying an external electric field (EF). We find that even relatively weak EF changes the magnetic...
Antiferromagnetic Cr2O3 is well-known for its room-temperature magnetoelectric behavior and has been proposed for data-storage applications [1]. Although bulk Cr2O3 is an antiferromagnetic Mott insulator with TN = 307 K, lms of Cr2O3 are reported to exhibit hysteresis loops with a moderate saturation of 33 emu/cm3 [33 kA/m] and significant coercivity up to 400 K (7.5 mT at 300 K) by Punugupati et...
