1. 6. Magnetoconductiivity of icosahedral AIPdRe at temperatures between 50-250 Kelvin

   University essay from KTH/Material- och nanofysik

   Author : Sana Ullah; [2013]
   Keywords : ;

   Abstract : The electrical conductivity of icosahedral Al70:5Pd21Re8:5 samples with residual resistance ratio RRR = p(4:2K)=p(295K), in the range from 10 to 220 are reported. The samples were manufactured by melting in an arc furnace and then annealed at 940 °C. One of the samples (RRR=10) was made by melt spinning. READ MORE

3. 7. Spin-FET based on InGaAs/InP heterostructure

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

   Author : Ricardo Moreira Salles De Andrade; [2011]
   Keywords : Spin; Spintronics; Field-effect transistor; Datta-Das transistor; Rashba effect; Low-temperature.; Physics and Astronomy;

   Abstract : A new design based on the spinFET proposed by Datta-Das was fabricated, using a channel defined by etching on a 2DEG material and nanomagnets as top-gates. The magnetotransports properties were measured at low temperatures. READ MORE

4. 8. Design and construction of ultrahigh vacuum system to fabricateSpintronic devices, fabrication and characterization of OMAR (organic magnetoresistance) devices

   University essay from Institutionen för fysik, kemi och biologi

   Author : Srikrishna Chanakya Bodepudi; [2009]
   Keywords : Organic spintronics; Organic based magnets; Magentoresistance; Organic magnetoresistance OMAR ;

   Abstract : This thesis concerns design and construction of an ultra high vacuum chamber to fabricate and characterize spintronic devices.  The long term intention is to fabricate spin valve structures with V[TCNE]2 (hybrid organic inorganic semiconductor room temperature magnet) sandwiched between two ferromagnetic electrodes, which requires better than 10-8mbar of vacuum.
