Orbital order induced ferromagnetic insulating properties
At temperatures below the metal–insulator transition of La1−xSrxMnO3 with 0.1 < x < 0.15, a peculiar ferromagnetic and insulating phase is observed which has been intensively discussed over the last few years. We present a detailed investigation of this phase by means of resonant and high energy x-ray scattering along with measurements of the electrical resistivity, thermal expansion, magnetiza...
متن کاملHigher order vortex gyrotropic modes in circular ferromagnetic nanodots
Magnetic vortex that consists of an in-plane curling magnetization configuration and a needle-like core region with out-of-plane magnetization is known to be the ground state of geometrically confined submicron soft magnetic elements. Here magnetodynamics of relatively thick (50-100 nm) circular Ni80Fe20 dots were probed by broadband ferromagnetic resonance in the absence of external magnetic f...
متن کاملSearch for ferromagnetic order in overdoped copper-oxide superconductors
In copper-oxides that show high-temperature superconductivity (HTS), the critical temperature (Tc) has a dome-shaped doping dependence. The cause of demise of both Tc and superfluid density ns on the overdoped side is a major puzzle. A recent study of transport and diamagnetism in a large number of overdoped La2-xSrxCuO4 (LSCO) films shows that this cannot be accounted for by disorder within th...
متن کاملSpin order manipulations in nanostructures of II-VI ferromagnetic semiconductors
Present spintronic research [1,2,3] involves virtually all materials families but ferromagnetic semiconductors are particularly attractive as they combine resources of both semiconductors and ferromagnets. We describe here recent studies of ferromagnetic Crand Mn-based II-VI diluted magnetic semiconductors (DMS) excluding, however, oxides that are subject of another presentation [4]. Properties...
متن کاملUltrafast Optical Manipulation of Ferromagnetic Order in InMnAs/GaSb
We have performed a two-color time-resolved magneto-optical Kerr effect (MOKE) study of a ferromagnetic InMnAs/GaSb heterostructure. We observed ultrafast photoinduced changes in the MOKE signal induced by a large density of spin-polarized transient carriers created only within the InMnAs layer using intense 140 fs mid-infrared pulses. Our data clearly demonstrates that magnetic properties, e.g...
