Název v původním jazyce

Tunneling magnetoresistance of hydrothermally sintered La1-xSrxMnO3- silica nanocomposites

Popis výsledku v původním jazyce

The study deals with tunneling magnetoresistance in a series of composite systems of so-called 0–3 connectivity, in which highly conducting manganite nanoparticles of ferromagnetic groundstate (0-dim objects) are embedded in the (3-dim) insulating matrix of silica. The sample fabrication included the sol-gel preparation of La1-xSrxMnO3particles of the x = 0.35 composition and 25 nm mean crystallite size, their coating by silica of controlled thicknesses in the 1–5 nm range, and subsequent consolidation by hydrothermal sintering at 300 °C. Temperature dependent electric resistivities of the materials were measured in magnetic fields of 0 and 40 kOe down to 5 K, and field-dependent isothermal curves were taken by sweeping magnetic field up to 140 kOe.
