Experimental Setup for Magnetoresistance Analysis of Lanthanum Manganites Thin Films

Oxygen transport in nanostructured lanthanum manganites.

Methods and models describing oxygen diffusion and desorption in oxides have been developed for slightly defective and well crystallised bulky materials. Does nanostructuring change the mechanism of oxygen mobility? In such a case, models should be properly checked and adapted to take into account new material properties. In order to do so, temperature programmed oxygen desorption and thermogra...

Weak localization and magnetoresistance of island-like thin copper films

Enhanced and oscillatory magnetoresistance of thin Fe„001... films

We have studied the magnetoresistance of single-crystalline 001 Fe films prepared by sputtering techniques and covered by epitaxial MgO or Pt protective layers. The influence of the thickness of the magnetic layer as well as of the nature of the capping layer on the Fe anisotropic magnetoresistance was investigated by four-terminal probe, measurements performed with the current J in the 110 mag...

Large magnetoresistance of electrodeposited single-crystal bismuth thin films

Single-crystal bismuth thin films 1 to 20 micrometers thick were fabricated by electrodeposition and suitable annealing. Magnetoresistance up to 250 percent at 300 kelvin and 380,000 percent at 5 kelvin as well as clean Shubnikov-de Haas oscillations were observed, indicative of the high quality of these films. A hybrid structure was also made that showed a large magnetoresistive effect of 30 p...
