Magnetic Heterostructures with Tunable Spin-dependent Transport Properties

Sahakyan A.S., Poghosyan A.V., Movsesyan R.M., Kocharian A.N., California State University Los Angeles, US

The transport properties in magnetic films consisting of alternating magnetic nanolayers separated by nonmagnetic quantum wells are studied for a definite finite number of (N) magnetic barriers consisting of two branches of ferromagnetically ordered structures. [...]

Multilayered nanostructures with controlled magnetic configurations

Sahakyan A.S., Movsesyan R.M., Kocharian A.N., California State University, US

We consider structures consisting of repeating ferromagnetic and nonmagnetic layers. The periodicity of the potential profile, consisting of alternating magnetic barriers and non-magnetic quantum wells, is broken by noncollinearity or noncomplanarity of the magnetizations of [...]

Resonance transmission of the electron wave through the nanofilms containing a magnetic quantum well

Sahakyan A.S., Movsesyan R.M., Kocharian A.N., California State University Los Angeles, US

The transmission of an electron wave through so called a magnetic resonance diode is considered in semiconductor nanofilms consisting of two nonmagnetic barriers separated by a quantum (magnetic) well subjected to an external magnetic field. [...]

Electronic properties in two dimensional quantum rings consisting of two nanoelements

Sahakyan A.S., Movsesyan R.M., Kocharian A.N., California State University Los Angeles, US

Electron spectrum and ground state properties in two dimensional confined quantum rings with R(1,2) radiuses (R1 les R2), consisting of the two different (material) nanoelements divided by two sectored finite size quantum wells with various [...]

The manifestation of the one-dimensional non-collinear spin-dependent scattering on magnetized nano-element structures

Sahakyan A.S., Movsesyan R.M., Kocharian A.N., California State University Los Angeles, US

The transfer-matrix approach is used to investigate the scattering of spin-polarized electron and neutron waves on the simple magnetized nanoelement structures which energetic profiles presents a finite potential magnetic barrier, in particular, of rectangular form. [...]
