On the basis of an ab initio theory of metallic magnetism in layered materials, we investigate the onset of magnetic order in thin (2-8 layers) fcc-Fe films on and embedded in Cu(100) substrates. In particular, we find an oscillatory dependence of the Curie temperatures on embedding depth, in excellent agreement with experimental data. The thermally induced spin fluctuations are treated within ...

The effects of low-temperature annealing and oxidation of the dilute magnetic semiconductor Ga1−xMnxAs are studied by photoemission spectroscopy in the hard x-ray regime HAXPES , with special attention to the depth profile of both concentration and chemical state of manganese. Annealing of Ga1−xMnxAs in air at 190 °C for up to 150 h leads to an enrichment of manganese at the surface accompanied...

We study experimentally the electronic transport and magnetism of GaAs/InGaAs/GaAs quantum wells (QW) with remote Mn -layer. The 2D energy spectrum of the carriers is revealed by quantum Hall Effect measurements. The ferromagnetic ordering is evidenced by anomalous Hall Effect and direct magnetization measurements. A signature of this state is also observed on the temperature dependence of the ...

Objective: To carryout geophysical investigation in Igumale and Ejekwe area with the aim of estimating Curie point depth (CPD) then evaluating geothermal gradient heat flow to see if it is viable for exploration. Methods: Spectral analysis method was employed this research work. Findings: The results show that CPD varies between 1.111 17.402km. It observed Eastern part study (11 - 12.6km) shall...
