Modified magnetism in heterostructures of Cr<sub>2</sub>Ge<sub>2</sub>Te<sub>6</sub> and oxides

چکیده

We study the effects of interfacing van der Waals ferromagnet Cr 2 Ge Te 6 with oxide layers, such as NiO and MgO, in a few different configurations. For this, magnetic hysteresis curves, obtained by magneto optical Kerr effect, flakes similar thicknesses were evaluated. Compared to properties bare , we observed an increased perpendicular anisotropy enhanced Curie temperature /NiO heterostructure. In contrast, report little or no change /MgO where was exfoliated on top layer. Finally, strain is considered mechanism enhancement, formation wrinkles thin heterostructure Raman characteristics close indicated tensile strain, which consistent stronger ferromagnetism .

Voltage control of magnetism in multiferroic heterostructures.

Electrical tuning of magnetism is of great fundamental and technical importance for fast, compact and ultra-low power electronic devices. Multiferroics, simultaneously exhibiting ferroelectricity and ferromagnetism, have attracted much interest owing to the capability of controlling magnetism by an electric field through magnetoelectric (ME) coupling. In particular, strong strain-mediated ME in...

The strange magnetism of oxides and carbons.

Magnetism is not usually expected in simple sp oxides like MgO or in carbons like graphite. Yet basic intrinsic defects in these systems can be magnetic in ways that seem to be shared by more complex oxides. A second puzzle comes from reports of possible room temperature ferromagnetism in simple oxides, where experiments are not always in agreement. This paper discusses what determines whether ...

MAGNETISM. Imaging and control of ferromagnetism in LaMnO₃/SrTiO₃ heterostructures.

Oxide heterostructures often exhibit unusual physical properties that are absent in the constituent bulk materials. Here, we report an atomically sharp transition to a ferromagnetic phase when polar antiferromagnetic LaMnO3 (001) films are grown on SrTiO3 substrates. For a thickness of six unit cells or more, the LaMnO3 film abruptly becomes ferromagnetic over its entire area, which is visualiz...

Symmetrical interfacial reconstruction and magnetism in La0.7Ca0.3MnO3/YBa2Cu3O7/La0.7Ca0.3MnO3 heterostructures

We have analyzed the interface structure and composition of La0.7Ca0.3MnO3/YBa2Cu3O7/La0.7Ca0.3MnO3 trilayers by combined polarized neutron reflectometry, aberration-corrected microscopy, and atomic column resolution electron-energy-loss spectroscopy and x-ray absorption with polarization analysis. We find the same stacking sequence at both top and bottom cuprate interfaces. X-ray magnetic circ...
