Asymmetric ferromagnetic resonance, universal Walker breakdown, and counterflow domain wall motion in the presence of multiple spin-orbit torques
Linder, Jacob; Alidoust, Mohammad (Journal article; Peer reviewed, 2013)Measurement of the maximum blood flow velocity is the primary means for determining the degree of carotid stenosis using ultrasound. The current standard for estimating the maximum velocity is Pulsed Wave (PW) Doppler with ... -
Meissner effect probing of odd-frequency triplet pairing in superconducting spin valves
Alidoust, Mohammad; Halterman, K; Linder, Jacob (Journal article, 2014)Superconducting correlations which are long ranged in magnetic systems have attracted much attention due to their spin-polarization properties and potential use in spintronic devices. Whereas experiments have demonstrated ... -
Non-Fraunhofer Interference Pattern in Inhomogeneous Ferromagnetic Josephson Junctions
Alidoust, Mohammad; Sewell, Granville; Linder, Jacob (Journal article, 2012)Generic conditions are established for producing a non-Fraunhofer response of the critical supercurrent subject to an external magnetic field in ferromagnetic Josephson junctions. Employing the quasiclassical Keldysh-Usadel ... -
Phase-controlled proximity effect in ferromagnetic Josephson junctions: Calculation of the density of states and the electronic specific heat
Alidoust, Mohammad; Rashedi, Gholamreza; Linder, Jacob; Sudbø, Asle (Journal article; Peer reviewed, 2010)We study the thermodynamic properties of a dirty ferromagnetic S|F|S Josephson junction with s-wave superconducting leads in the low-temperature regime. We employ a full numerical solution with a set of realistic parameters ... -
phi-state and inverted Fraunhofer pattern in nonaligned Josephson junctions
Alidoust, Mohammad; Linder, Jacob (Journal article; Peer reviewed, 2013)A generic nonaligned Josephson junction in the presence of an external magnetic field is theoretically considered and an unusual flux-dependent current-phase relation (CPR) is revealed. We explain the origin of the anomalous ... -
Proximity effects and transport properties of nano-scale systems with multiple broken symmetries
Alidoust, Mohammad (Doktoravhandlinger ved NTNU, 1503-8181; 2013:359, Doctoral thesis, 2013) -
Singlet-triplet superconducting quantum magnetometer
Alidoust, Mohammad; Halterman, K; Linder, Jacob (Journal article, 2013)Motivated by the recent experimental realization of a quantum interference transistor based on the superconducting proximity effect, we here demonstrate that the inclusion of a textured ferromagnet both strongly enhances ... -
Spin-polarized Josephson current in superconductor/ferromagnet/superconductor junctions with inhomogeneous magnetization
Alidoust, Mohammad; Linder, Jacob; Rashedi, Gholamreza; Yokoyama, Takehito; Sudbø, Asle (Journal article; Peer reviewed, 2010)We study numerically the properties of spin transport and charge transport in a current-biased nanoscale diffusive superconductor/ferromagnet/superconductor junction when the magnetization texture is nonuniform. Specifically, ... -
Spin-triplet supercurrent through inhomogeneous ferromagnetic trilayers
Alidoust, Mohammad; Linder, Jacob (Journal article; Peer reviewed, 2010)Motivated by a recent experiment [J. W. A. Robinson, J. D. S. Witt, and M. G. Blamire, Science 329, 5987 (2010)], we report here the possibility of establishing a long-range spin-triplet supercurrent through an inhomogeneous ... -
Superconducting phase transistor in diffusive four-terminal ferromagnetic Josephson junctions
Alidoust, Mohammad; Sewell, Granville; Linder, Jacob (Journal article, 2012)We study diffusive magnetic Josephson junctions with four superconducting terminals in the weak proximity limit where the leads are arranged in cross form. Employing the linearized Keldysh-Usadel technique, the anomalous ... -
Tunable supercurrent at the charge neutrality point via strained graphene junctions
Alidoust, Mohammad; Linder, Jacob (Journal article; Peer reviewed, 2011)We theoretically calculate the charge-supercurrent through a ballistic graphene junction where superconductivity is induced via the proximity-effect. Both monolayer and bilayer graphene are considered, including the ...
